For my company, we're using a on-the-server search engine to let customers search our site. We're using an internal one to keep them on our site while they search. We've been using ht://dig but I'm not really pleased with the results. While looking around, I'm not finding different search engine projects all that easily. Does anyone have any suggestions for free/OSS search engine software for a LAMP (Linux/Apache/MySQL/PHP) server?
I was afraid of that. I mean, ht://dig works -- but it's just really archaic and a pain to integrate into a PHP-driven site. I've found a project called TSEP (http://tsep.sf.net) which even appears to be worked on regularly! However, I don't think anyone in charge of coding speaks English . . . and it doesn't work on install . . .
As far as buying Google's search applicance, my boss is a ridiculous cheapskate. If it's not free, he's not interested.
If I can get TSEP working, I'll share my results here.
You Mac users probably know about this already, but in case you didn't, go here: http://www.macheist.com/ There's a bunch of software that they normally charge for, only it's freeeeeee for the next few days.
