The second (assuming you means CONTAINS, and actually put it in a valid query) should be faster, because it can use some form of index (in this case, a full text index). Of course, this form of query is only available if the column is in a full text index. If it isn't, then only the first form is available.
The first query, using LIKE, will be unable to use an index, since it starts with a wildcard, so will always require a full table scan.
The CONTAINS query should be:
SELECT * FROM table WHERE CONTAINS(Column, 'test');
Answer from Damien_The_Unbeliever on Stack OverflowThe second (assuming you means CONTAINS, and actually put it in a valid query) should be faster, because it can use some form of index (in this case, a full text index).

The CONTAINS query should be:

Having run both queries on a SQL Server 2012 instance, I can confirm the first query was fastest in my case.
The query with the LIKE keyword showed a clustered index scan.
The CONTAINS also had a clustered index scan with additional operators for the full text match and a merge join.

Rather slow, but working method to include any of words:
SELECT * FROM mytable
WHERE column1 LIKE '%word1%'
OR column1 LIKE '%word2%'
OR column1 LIKE '%word3%'
If you need all words to be present, use this:
SELECT * FROM mytable
WHERE column1 LIKE '%word1%'
AND column1 LIKE '%word2%'
AND column1 LIKE '%word3%'
If you want something faster, you need to look into full text search, and this is very specific for each database type.
Note that if you use LIKE to determine if a string is a substring of another string, you must escape the pattern matching characters in your search string.
If your SQL dialect supports CHARINDEX, it's a lot easier to use it instead:
SELECT * FROM MyTable
WHERE CHARINDEX('word1', Column1) > 0
AND CHARINDEX('word2', Column1) > 0
AND CHARINDEX('word3', Column1) > 0
Also, please keep in mind that this and the method in the accepted answer only cover substring matching rather than word matching. So, for example, the string 'word1word2word3' would still match.
