I just noticed that one of my Stackoverflow-search-bookmarks no longer displayed all the questions in the tags I want. After some experimenting I could reduce it to the following issue:
It used to be that if you visited the page /questions/tagged/foo or bar baz
, the performed search would be foo OR (bar AND baz)
, however somewhat recently it must have changed to (foo OR bar) AND baz
, which broke my bookmark.
I think the old behavior was preferable because:
- Traditionally (i.e. in maths and most programming languages) AND binds tighter than OR.
- It is IMHO the more useful behavior.
- The tag list at the right of the tagged-page (see screenshot below) definitely makes it look as if you were searching for "questions tagged foo or questions tagged bar and baz", not "questions tagged foo and baz or questions tagged bar and baz" (which is the new behavior).
If this change was indeed intentional, I would at least ask that the list of searched tags is changed to visually indicate the new behavior (either by adding parentheses or by changing it to display as "foo baz or bar baz").
