Anyone Know of a Free Site Search?

I'm looking for a free site search engine. One that requires very little up-keep and doesn't spam my users with ads. Ideally it would be easy to implement, easy to maintain, and not require any massive installation procedure.

Also, I am trying to avoid google custom search.

Please let me know of any products that you think wo开发者_运维知识库uld satisfy those requirements!

Thanks

You can use perlfect Search from sourceforge.net

Perlfect Search is a free, sophisticated, powerful, versatile, customizable and effective site indexing/searching suite available under an open source license (GPL).

It comes as a pair of distinct scripts. The indexer, that automatically scans and indexes a web site, and the search engine, a cgi script that serves search queries for keywords over the index, and displays results pages in html, in a standard format including title, description and relevance ranking for each matching document. Advanced features include stopwords, a potent exclude mechanism and a handy automatic installation and configuration utility.

Download: You can download Perlfect Search in either tar.gz (Linux/Unix) or zip (Windows) format:

"Easy to implement and maintain" are a bit relative, so I'm not sure where your threshold lies. But if you rule out things such as Google CSE (and similar offerings from other search engines), then you need to consider installing some search software on your servers and doing the indexing yourself.

One can get started with Apache Solr very quickly if you are prepared to write some scripts to bulk index your site content into it. If you want a tool to crawl your site for you and index it, then Apache Nutch is a solid choice. I've installed it a used it to crawl and search a website in less than one day. Extra bonus for combining Solr with Nutch (read up here and here). I hear their latest integration is more seamless than ever now that Solr has been rolled into Lucene.

If you don't mind crawling your own pages, you could implement your own with Lucene. Lucene is a great open-source full-text search engine, and the advantage to using it is you can do things your way. It's quite easy to use after spending 15 minutes reading some tutorials.

It's available for Java and .NET (and others).
