Notice in these two images that in both, I am filtering by the word "finalize" but in one image, Jira tells me there are 696 matches and in the other screen it says there are only 7. Only one of these screens should be possible to get (see the secret below):


The secret is that I made one of them by typing "finalize" in the text field and TABBING out of the field, and I made the other by typing RETURN on the field.
I suggest JIRA perform the search as soon as I leave the field, regardless of whether I use TAB or RETURN. That would solve the issue.
