Highlight filepath matches in the filename display

[keegancsmith]

Reproduction on public instance. This should have no matches, but instead it is returning a single match for line 0, but that is not the line.

this is working as intended, albeit not documented.

"str"

gets expanded to

(OR file:"str" content:"str")

if you want to search for content specifically, you can use

content:mapreduce

This has two reasons:

• better search quality
• it creates a place for highlighting matches on the filename.

I'm open to suggestions on how to make this more obvious.

Yeah that makes a lot of sense. I think the bit that is surprising to me is how it is displayed in the UI, where it looks like another line match.

Happy for a patch that changes the display too. Maybe we could do match highlighting on filenames in general.
