I have noticed that the settings on your most recently opened Search tab (Match case, Match all word forms) affect inline searches, but it is not evident from within inline search that something like this might be affecting your search results, and there is no way to change it from there. I had a case of that recently. It's odd to have to go open another Search tab to change this setting when you're getting unexpected results from inline search. There should be a way to change those search settings from the inline search bar.
