Relevanssi – A Better Search

Relevanssi replaces the standard WordPress search with a better search engine, with lots of features and configurable options. You’ll get better results, better presentation of results – your users will thank you.

This is the free version of Relevanssi. There’s also Relevanssi Premium, which has added features. For more information about Premium, see Relevanssi.com.

Do note that using Relevanssi may require large amounts (hundreds of megabytes) of database space (for a reasonable estimate, multiply the size of your wp_posts database table by three). If your hosting setup has a limited amount of space for database tables, using Relevanssi may cause problems. In those cases use of Relevanssi cannot be recommended.
