how to search for a specific file type/extension

[idkaname]

like for a specific game file type's scenes, like .phz for algodoo, also I don't want to search for jsut the extension to show all of the files ,but i wat to input a name THEN search, like as if i put on a specific extension or file type to search for (like .phz) mentioned above, then search for the name, like for example, searching for .phz fiels only and type i na name and it finds the name of ONLY .phz file since it's filtered onto it thx

Search within search? it is on my TODO list.

(I'm kind of confused...)

ext:phz, will find phz files.
ext:phz red, will find red phz files.

You can set up a filter, call it, say, "phz", that is: ext:phz, & on selecting that filter, a search for "red" will find, red phz.
