Boolean conditions are not working in my desktop version of Zotero: only the "AND" operator seems to function, regardless of whether I select "All" or "Any". Have you encountered the same problem? (Zotero 7.0.2 (64-bit))
If you actually mean 7.0.2 you'd have to update to the most recent version. Beyond that, we'd want a screenshot of the search and a bit more detail about what is going wrong
In 7.0.2, when I add a keyword to broaden the search, with "any" in option it behaves like an AND condition (all). The number of results goes from 138 to 36.

I tried using the "all" condition, in case it was a translation issue from English to French, but the result is the same (36 results).
Search 1: term 1
Search 2: term 2
When combining searches 1 and 2 within collections, the results are displayed correctly in "any term" mode. Therefore, the problem seems to only occur when searching "across all Zotero fields".

Search 1: term 1 in Title (68 results)
Search 2: term 1 in Abstract (71 results)
Combining searches 1 and 2 using the OR operator yields the expected results (106 results)
