Best way to search in a varchar column in sql server

What would you recommend to search a sql server table (varchar(max) column) for a term?

Let's say, like in ebay, if you search for "wii brand new", you get results like "Brand New Nintendo Wii Fit Game + Balance Board Bundle", "Wii Fit (Wii) BRAND NEW WII FIT GAME + BALANCE BOARD".

I think it basically searches every word and returns the ones that contains all the words, what would you recommend?

Depends on what you are trying to do. For a simple search, you could just do select * from table where field like '%word%'. But if this is some sort of application feature, you want to look into a full tet search application. It can store words that appear in that field as indexes and then search accross those words instead of using that field.

You are looking for fulltext indexing, it allows you to do more advanced querying than regular expressions or like.

Check this article for a quick introduction, the instructions are for SQL Server 2000, where it is a little harder to setup than in 2005 or 2008.

Relevant quote:

 With full-text searching, you can perform many other types of search:

 * Two words near each other
 * Any word derived from a particular root (for example run, ran, or running)
 * Multiple words with distinct weightings
 * A word or phrase close to the search word or phrase
