PubMed: Using the Search Filters

Getting Started with Search Filters in Sourcely

Sourcely’s filtering system is designed to make navigating its database of over 200 million research papers straightforward and efficient. Here’s how you can make the most of its filtering options.

How to Navigate the Filter Interface

Start by pasting your text into the search bar and clicking 'Find Sources.' In just about ten seconds, Sourcely will generate a list of relevant results. For example, when researcher Sophia Sipos tested the system in March 2025 with a 1,000-word paper on bioacoustics, the platform delivered results almost instantly.

Once your results are ready, click the 'Filters' button to narrow down your search. According to Sipos:

"If you want to filter the search, simply click 'Filters' and apply relevant fields. In this example, I left the filters clear."

After clicking the button, you’ll see a variety of filter options. You can apply several filters at once and watch your results update in real-time. Sourcely also offers sorting tools that work alongside these filters. You can organize results by relevance, publication year, citation count, or even alphabetically by title. This combination of filtering and sorting gives you full control over how you view and prioritize research materials.

By starting with the filter button, you unlock a wide range of tools to refine your search and focus on the most relevant research.

Understanding Filter Types

What sets Sourcely apart is the variety and depth of its filtering options. These filters are designed to meet the diverse needs of academic researchers, making it easier to find exactly what you’re looking for.

Publication-based filters allow you to refine results by publication year or author. If you’re looking for the latest studies or want to focus on a specific time period, these filters are invaluable. You can set custom date ranges to explore recent developments or historical trends, depending on your research needs.

Relevance and citation filters are perfect for pinpointing influential sources. By filtering based on citation counts, you can prioritize highly-cited papers that carry weight in the academic community. This ensures you’re working with sources that are both credible and impactful.

Keyword refinement filters provide an additional layer of precision. The Science Grad School Coach highlights this feature:

"What sets Sourcely apart is its advanced filtering system. Not only can you filter by publications and citations, but you can also include or exclude specific keywords to refine your search."

This functionality allows you to include terms that must appear in your results or exclude terms to filter out irrelevant content. It’s especially useful when dealing with topics that have multiple interpretations or when you need to avoid certain subtopics.

Sourcely also integrates Boolean operators into its filtering system, giving you even more control. Use AND to ensure multiple terms appear together, OR to expand your search to related concepts, and NOT to exclude specific terms. For complex searches, you can group related terms with parentheses and use quotation marks to find exact phrases.

Setting Up Filters for Better Results

Fine-tuning your search filters can help you zero in on the most relevant and precise results for your research.

Setting Date Ranges and Publication Types

Using date ranges is a smart way to balance between recent advancements and foundational studies. If you're working in fast-evolving fields like artificial intelligence or medical research, narrowing your search to the past 2–3 years can ensure you're accessing the most up-to-date findings. On the other hand, for historical or theoretical studies, expanding the range allows you to include key foundational work.

Changes in publication policies - like the introduction of mandated Data Availability Statements in 2015 and 2018 - illustrate how filters based on date and publication type can help you find sources that align with specific quality standards. By combining these filters, you can pinpoint studies that meet evolving academic requirements.

Publication type filters add another layer of precision by focusing on the format of the work. For example, selecting "Review" will highlight systematic reviews and meta-analyses, while "Clinical Trial" narrows your results to studies with controlled experimental designs. However, keep in mind that some relevant results might be missed if indexing processes, such as MeSH term assignments, are incomplete.

Once you've set these filters, you can further refine your search by incorporating citation counts and Boolean operators.

Using Citation Counts and Boolean Operators

Filtering by citation count can help you identify influential studies. Citation analysis, which looks at how often a study has been cited, is a useful way to gauge its impact and relevance. Start with a broad search, then sort the results by citation count to highlight the most referenced papers. Keep in mind that newer studies may not have had enough time to accumulate citations, so it's important to balance citation thresholds with the recency of publications.

Different databases handle citation counts differently. For example, Google Scholar may show inflated numbers due to duplicate entries or inclusion of non-journal sources. Meanwhile, Web of Science indexes over 9,300 scholarly journals, and Scopus is recognized as the largest abstract and citation database. Understanding these differences can help you set appropriate citation thresholds when using tools like Sourcely.

Boolean operators provide a powerful way to combine search terms with precision. Tony DeFilippo from the University of Nevada, Reno, explains:

"When searching online databases, you often get too many or too few results. Identifying keywords or phrases and then connecting them using Boolean operators (AND, OR, and NOT)... can help you narrow, expand, and/or refine your searches to find relevant, useful sources."

Using operators like AND, OR, NOT, and parentheses for grouping allows you to refine your searches even further . When combined with date ranges and publication type filters, Boolean operators enable you to craft highly targeted searches that deliver exactly what you need for your research.

Creating and Saving Custom Filter Sets

Once you've fine-tuned individual filters, you can combine and save those settings to simplify future searches. By mastering the essentials - like date ranges, publication types, and Boolean operators - you’ll find that creating custom filter sets not only saves time but also eliminates the need to repeatedly configure the same criteria. This means you can quickly apply your tried-and-true filters across different projects with ease.

Building Filter Sets for Different Research Needs

Every research project has its own unique requirements, so your filtering approach should match the task at hand. For example, literature reviews often call for broader filters that cover a variety of publication types and longer date ranges. On the other hand, systematic reviews demand narrower filters, focusing on specific study designs or higher citation counts. You can tailor your templates by choosing keywords, publication years, or even specific authors to align with the goals of each project.

Let’s say you’re investigating educational technology but want to exclude studies on early childhood education. You could create a filter set that includes terms like "educational technology" while excluding keywords such as "preschool" or "kindergarten." This level of customization allows you to design templates for specific purposes - whether you're zeroing in on recent publications about emerging technologies or gathering foundational works for a historical perspective. Excluding irrelevant keywords ensures your results stay focused and relevant.

Saving and Sharing Your Filters

Once your filters are set, you can save them under a descriptive name that reflects the project or research type. For instance, you might name a filter set "Systematic Review - Clinical Trials 2020–2024" or "Literature Review - AI in Education - Broad Search." These saved filter sets are linked to your account, making it easy to switch between them using a dropdown menu. As your research evolves, you can modify these filters or reset them back to their original settings.

Sourcely also allows you to share custom filters with your team. While only the creator can edit a shared filter set, team members can save their own copies if they need to make changes. This ensures consistency in research protocols while still offering flexibility for individual adjustments.

To further streamline your workflow, you can organize saved sources into folders. This feature works hand-in-hand with your custom filter sets, making it easier to categorize and manage search results. With access to over 200 million credible academic papers, Sourcely’s tools are designed to help you conduct research more efficiently across a variety of projects.

Fixing Common Filter Problems

Even with thoughtfully created filter sets, search issues can still crop up, disrupting your workflow. The most frequent challenges? Either ending up with a flood of irrelevant results or struggling to find enough useful sources. The good news is, with a few tweaks, you can quickly get things back on track.

Fixing Too Many or Too Few Results

If you're drowning in irrelevant results, it’s often because your keywords are too broad or your filters aren’t specific enough. A great first step is to refine your keywords to better match your research focus. For example, if you're researching "nursing" as a profession but keep stumbling across articles about nursing mothers, you can use the NOT operator to exclude "mother" from your search. This simple tweak can instantly cut out hundreds of unrelated results.

Phrase searching is another powerful tool to narrow down broad results. Instead of searching for multiple terms like artificial intelligence education, use quotation marks to look for the exact phrase "artificial intelligence in education". This ensures the words appear together in the exact order, significantly reducing irrelevant matches.

Did you know that 90% of published search strategies contain at least one error, and 80% of those errors impact search effectiveness? A common mistake is misusing Boolean operators. To make sure all your keywords appear in the results, use "AND" between terms. For instance, searching for "machine learning" AND "student assessment" AND "higher education" guarantees that all three concepts are included in your results.

On the flip side, if you're getting too few results, it may help to relax some of your filters. Narrow date ranges or overly specific publication types can limit your findings. For example, if you're searching for studies on educational technology from 2023-2024 and coming up short, try expanding the date range to 2020-2024 or removing the date filter altogether.

Another tip: simplify your search terms. Overloading your query with too many keywords can unnecessarily complicate your strategy, filtering out useful papers. Focus on the essential components of your research question, and then broaden the search by using OR with synonyms. For example, try (online learning OR e-learning OR distance education). Wildcard symbols like asterisks can also be helpful - searching for educat* will include variations like "education", "educational", and "educator".

Lastly, make it a habit to update your filters regularly to keep up with the latest research trends.

Updating Filters for Current Research

Research evolves quickly, and if your filters don’t keep up, you risk missing out on essential developments. What worked six months ago might now overlook key studies or use outdated terminology. Regularly revisiting and updating your filter sets ensures you're staying on top of the most relevant research.

Start by checking out recent subject terms and keywords in your field. New terms often emerge as research progresses, and ignoring them can create gaps in your searches. For instance, if newer studies use "generative AI" instead of "artificial intelligence", make sure to update your filters to include both terms.

Keep in mind that database indexing speeds can also affect your search results. Even though platforms like Sourcely provide access to over 200 million academic papers, different databases index new publications at varying rates. To avoid missing newly indexed content, plan to revisit and rerun important searches periodically.

Field-specific changes can also impact your filters. If your area of research is growing rapidly, you might need to add more exclusion terms to maintain quality. On the other hand, emerging fields might require broader terms to capture the developing literature.

“Plan search strategies by consulting the MeSH database to select appropriate terms, both descriptors and synonyms, and combining search techniques in the free-text and controlled-language fields, truncating the terms appropriately to retrieve all their variants.” – José Antonio Salvador-Oliván, MD, PhD

Finally, if you're working on a team, establish a regular review schedule for shared filter sets. Assigning one person to maintain and update these filters ensures consistency and helps everyone benefit from improved search strategies as projects evolve.

FAQs

How can I use Boolean operators to refine my academic research search results?

Boolean operators are an excellent tool to sharpen your search results and make academic research more targeted. Here's a quick guide to using them:

• AND: Use this to combine terms and narrow your search. For example, typing climate change AND policy will display results that include both terms together.
• OR: This operator expands your search by including either term. A query like climate change OR global warming will return results containing one term or the other.
• NOT: Exclude specific terms to filter out irrelevant content. For instance, climate change NOT politics will remove results that mention politics.
• Parentheses: Group terms for more detailed searches. For example, (climate change OR global warming) AND (policy OR legislation) ensures your search is well-organized and precise.
• Quotation Marks: Use these to search for exact phrases. For example, "climate change impacts" will only show results that include that exact phrase.

Mastering these operators can save you valuable time and help you zero in on the most relevant research for your needs.

How can I keep my search filters updated to match current research trends?

To keep your search filters relevant and in sync with the latest research trends, it's essential to review and tweak them regularly. Start by using controlled vocabularies specific to your research database, like MeSH terms in medical databases, and fine-tune your search syntax as necessary. Be cautious about applying overly narrow filters - such as restricting by publication date or language - as these might unintentionally exclude important findings.

Stay adaptable by adding new keywords, methodologies, or emerging terms that are gaining traction in your field. Revisiting your filters periodically ensures they stay effective and aligned with the latest advancements, helping you achieve more precise and relevant academic research outcomes.
