Personally I use glimpse for this.  It's a bit old and creaky but it
performs wonders.  There might be something better out there by now.

I wouldn't recommend trying to use a standard FTS to index code:
code is not a natural language and the kinds of searches you usually
want to perform are a lot different.  As an example, I glimpse for
"foo" when looking for references to a function foo, but "^foo"
when seeking its definition (this relies on the coding conventions
about function layout, of course).  An FTS doesn't think start-of-line
is significant so it can't do that.
