优雅的搜索方式（PHP + MySQL）

Question

We have a website written in Codeigniter framework. Now we want to have a nice and fast soundex based search function to the site. It's just a micro blog so we would only search in the titles of the posts.

So what would be the best for us?

I have two ideas:

1. Create another column in the post table with the soundex copy of the title and simply have FULL-TEXT index on it.

2. Explode the words from the titles and save the soundex equivalent of the words in a new table with the id of the post. Just like an automatic tag system.

Which method is the better and why? Can you suggest a better way?

Thanks for all the answers!

Answer 1

Soundex is great - but it usually doesn't meet user expectations for search (established by Google etc.).

The common solution to text searching, including fuzzy searches and stemming, is to use something like SOLR ; it's relatively easy to integrate with PHP using web service calls.

The Zend framework has Lucene integration (never used it, but it might save you some time) - Lucene is an open source free text search platform .
