Internal Searches on Windows 2000 Server / Apache

Hi. I am trying to implement a search feature for a corporate website, but haven't found anything that is viable. My main problem seems to be that there are fewer options out there for PHP/Apache/Windows. ht://dig is not available for Windows. The Google Web API has several limitations which we wouldn't want(Such as: only 10 results per query, Limit of 1000 requests per day, possibly buggy code as it's still in beta) I've also considered writing my own code to index all the pages and put them in a DB for the search. I feel confident I could do it, but it would take a long time and would be much better if there was another solution out there. Are there any other options out there for me? I'm open to just about anything. Thanks, Chris
