How to improve WordPress search

I heard many times, that WordpPess’s search doesn’t work good.

Are there any other search engines available for wordpress?

I know about sphynx, seems its a good one, but available plugins are out of date.

There are a lot of a posts written about this, and it took me a while to figure out a solution. Google Custom Search is a great solution – if you have a google account (which you can easily get if you don’t), a basic understanding of wordpress themes, and some php.

If you don’t have those skills sets, there is a pretty good plugin you can use. It’s not as good as Google Custom Search, but it does the job better than the WordPress’s search engine.

Hope this helps a bit.

Using a dedicated search engine like sphinx or solr You can improve search result.

The most common one at the moment is, I think, Google Custom Search.

I personally like a lot the Search Unleashed plugin. Simple and efficient. It does need a bit of patching unfortunately, because the author seems to have given up.
Fortunately, the patch can be found on the wordpress forum, in this thread.
