Only programatically, the limits are defined here:

In the primary/initial view, each file type is shown in a separate 
category, but you can't JUST limit it to one category right now.

Yes.

In tracker-search:
File extension is more accurately done with nie:mimeType because unlike 
extensions, implementations detecting file mime types can use binary 
blobs and other mechanisms to detect the actual content type.

You could also use a regular expression on nfo:fileName. Paths can be 
filtered or queried using nie:url too. There are other functions 
available here too:

In tracker-needle:
Extension searching may work using '*.txt', I'm not sure.
Path searching is possible using the second icon from the left.
