if you've found (like i have) that IGT's forum search couldn't find an elephant even if they were sitting next to it in a maruti, and find it to be completely useless, then why not use google? it works much better! heres what you do:
type the following into the google search bar:
for example if i wanted to find chords for "tu kaun hai" by lucky ali, i'd type the following into the google search bar:
tu kaun hai site:www.indianguitartabs.com
tu kaun hai chords site:www.indianguitartabs.com
or something along those lines.
