Search-string builder
Break your topic into concepts, list a few synonyms for each, and BLOOM assembles a copy-ready Boolean search string. Synonyms within a concept are joined with OR; concepts are joined with AND. Paste the result into any library database.
Build your search string
Enter a main keyword for each concept and up to four related terms. Empty rows and empty boxes are ignored. Watch the live preview below.

A worked example
Say you’re researching how social media affects how teenagers feel about their bodies. Break that into three concepts, each with a few synonyms:
- Concept 1:
social mediaORInstagramORTikTok - Concept 2:
teenagersORadolescentsORyouth - Concept 3:
body imageORself-esteem
Joined together, the builder hands you:
Paste that into a database’s search box and it finds records that mention at least one term from every concept. (Those are the placeholder values in the boxes above – clear them and type your own.)
Boolean in the age of AI
AI-powered discovery layers and chat search are happy to take a plain-English question, and that’s useful for getting oriented. But most library databases still reward a precise keyword-and-Boolean string: it’s transparent, reproducible and easy to tweak when results are too broad or too narrow. Use natural language to explore, then bring a deliberate Boolean string here for the focused database search that a literature review or systematic search needs.
