Query Text

Hi Experts!

Say I needed to look through 500K flat files (each no larger than 3KB)
So, I created a table (Msg_tbl) with a feild called "msgtxt" as a text field.

The idea is to load each file into the table.

How do you query the field "msgtxt" if you want to find phrases such as "out of the blue"?

This is for SQL 2008.

are you wanting to search for '%out of the blue%' or are you looking for similar phrases, phrases with the same.similar meaning?

 in which case you nmay wish to consider establishing a fulltext index over the column and using the full text search keywords
e.g. contains....

if you are trying to do a "LIKE" search do you need to worry about punctuation between the words of the phrase?
