SSRN’s search has been sorely in need of some love for a while, so we’re very happy to share that we’ve recently been able to make some improvements to how it works. Previously, if you wanted papers about corporate governance but not banking, you couldn’t say so. If your search terms were slightly off, you may have struggled to find what you’re for. We’ve now added two new search modes to the Advanced Search page: Fuzzy Search and Boolean Search. They solve different problems, and you can choose between them depending on what you need.
Fuzzy Search: A Broader Net
Fuzzy Search is more forgiving than a traditional keyword search. It will tolerate slight variations in your search terms, typos, and near-matches, returning results that a strict search might miss. You’ll typically see a larger set of results, which makes it useful for exploratory searches, when you’re not yet sure of the precise terminology a field uses.
It works across all three search field options (Title Only, Title Abstract & Keywords, and Title Abstract Keywords & Full Text) and applies to the Author(s) field as well. If your query is in the right neighbourhood, fuzzy matching will try to get you there. A word of calibration: fuzzy search broadens your results, but it isn’t a spell-checker. It works best when your terms are close to the target. The further off your query, the noisier the results
Boolean Search: A Precise Tool
Boolean Search lets you build structured queries using standard logical operators:
AND requires both terms to appear. "corporate governance" AND disclosure returns only papers addressing both topics.
OR broadens to either term. "machine learning" OR "deep learning" captures papers using either framing.
NOT excludes a term. cryptocurrency NOT bitcoin finds crypto papers that aren’t specifically about Bitcoin.
Parentheses let you group expressions. (fintech OR regtech) AND regulation finds regulation papers that mention either fintech or regtech, without running two separate searches.
As with Fuzzy Search, Boolean mode works with all three advanced search options. Narrow your scope to Title Only for precise results; expand to Full Text to surface papers where the terms appear anywhere in the document.
Two Modes, One Search
These are separate modes, not features you stack. You choose one via the radio buttons on the Advanced Search page. The right choice depends on where you are in your research.
Use Fuzzy Search when you’re exploring a new area, working from partial memory, or casting around for how a topic is discussed in the literature. It’s the mode for early-stage discovery, when missing a relevant paper is worse than wading through some noise.
Use Boolean Search when you know what you’re after and want to carve out a specific slice of the literature. It’s the mode for systematic reviews, targeted citation searches, and any query where you need to include or exclude particular terms with confidence.
Both modes share the same controls: scope selection, the Author(s) field, date filters, and sort options. The only difference is how the search engine reads your query.
A Two-Step Workflow for Search
You can now think in terms of a two-step workflow for Search on SSRN. Start in Fuzzy Search with a broad query. Scan the first page of results to pick up the vocabulary the literature actually uses. Then switch to Boolean Search and build a precise query with those terms and operators. The two modes complement each other when used in sequence.
In Boolean mode, wrap multi-word phrases in quotes: "corporate governance" behaves differently from the two words searched separately. And remember that the Author(s) field is independent of the main search box. If you want a specific person’s work on a specific topic, use both fields rather than cramming everything into one query.
These changes are live now on papers.ssrn.com, and we really hope you find them useful. Send us your feedback at ideas@ssrn.com, we’d love to hear from you.
