I am totally annoyed by JIRA search every time I search. It has lots of issues,
but I think a big one is that it defaults to OR search. I end up placing
+ sign before every search term to simulate more reasonable AND search. Every
other major search engine in the world uses AND search by default.
I have filed an issue to change default JIRA search to AND; it's at http://jira.atlassian.com/browse/JRA-5930
- if you are interested in improving JIRA search you should vote for it.
