script for indexing .doc files, +search box to search them....

[Fking]

here is the situation
i have over 100mb doc, txt, rtf documents, (mainly .doc) with useful information
i want to put them all in a dir on my website

and give to my surfers the possibility to search them all (not only the file name, but the text inside) via search box

please recommend me a script to do that.
i guess if it searches everytime all the docs, this will load very heavy the processor, so i'll prefer, a option, to index them all once, and after that just refresh, periodicaly or on update....or something like that......

Unless you're going to either save all the .doc files as .txt (on a Windows machine you could probably use COM functions to do this if you have a copy of Word on it) so that you have something to search (or perhaps use COM and Word directly), you'll have to consider sucking up to Microsoft to get the details of their (closed for "security reasons") .doc format, and/or find someone else who has already reverse-engineered the format and written something that can be used (it would probably be a separate application - you wouldn't want to do it in PHP).

FYI, you can use antiword to convert the .doc files to plain text, even on non-Windows platforms:
