[web2py] how to make incremental search using ajax?

[rafael]

hello

I would like to make incremental search using ajax like below link.
http://sphinx.pocoo.org/search.html?q=python

Currently I made search function using grep tool through Popen python
function following code.

def result():
   from subprocess import *
   pipe = Popen( "grep -R -n \"web2py\" *, shell=True, stdout=PIPE)
   return TABLE(*[TR(result) for result in
pipe.stdout.read().splitlines()])

But it's not working when loading a lot of files.

So I wanna make incremental search function.

Thanks in advance.
