Site Search Facility

[eluser]benmanson[/eluser]
Hi,

I'm looking to add search functionality to sites I am building with CI and am looking for recommendations for the best way to implement it. Should I code it myself or is there an existing library I could use, or is it best to use an external search engine? My sites are built with my own CMS and data is all stored in MySQL tables.

Any recommendations would be appreciated.

Thanks
Ben
