Performance of Like '%Query%' Vs Full Text Search CONTAINS Query?

Full Text Searching (using the CONTAINS) will be faster/more efficient than using LIKE with wildcarding. Full Text Searching (FTS) includes the ability to define Full Text Indexes, which FTS can use. Dunno why you wouldn't define a FTS index if you intended to use the functionality...

For a typical database, the CONTAINS search can be much faster assuming the appropriate full text search index is built on the field being searched. The evaluation of the LIKE operator generally doesn't use an index and thus must read all the data.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
