Debian source search by file name

[Tong Sun <suntong001@users.sourceforge.net>]

Hi,

Is it possible to do Debian source search by file name?

I wanted to see examples of overriding
debian-watch-does-not-check-gpg-signature in
debian/source/lintian-overrides files, so I did:

https://codesearch.debian.net/search?q=path%3Adebian%2Fsources%2Flintian-overrides
https://codesearch.debian.net/search?q=gpg+signature+path%3Adebian%2Fsources%2Flintian-overrides

But none gave results I want. Both say:

. . . had no results. Please read the FAQ to make sure your syntax is correct.

I think my syntax is correct, right?
