What is the SQL used to do a search similar to “Related Questions” on Stackoverflow

Question

I am trying to implement a feature similar to the "Related Questions" on Stackoverflow.

How do I go about writing the SQL statement that will search the Tit

Answer 1

It's probably done using a full text search which matches like words/phrases. I've used it in MySQL and SQL Server with decent success with out of the box functionality.

You can find more on MySQL full text searches at:

Or just google Full Text search and you will find a lot of information.
