We have QuickIndex which is free. We are still sort of working on it, ironing out bugs and adding new stuff.
QuickIndex has a search feature, which might be what you are looking for.
Thank you! This was VERY helpful. I used one of the scrips and it worked like a charm.
Thanks Pickory. Best of luck with your QuickIndex! While it wasn't what I wanted it to do, it is very cool.
