Possible to Partition Strings ?

Hello:

I am attempting to develop a database to hold a large number of rows of file names and related information. The main table being searched would be a master name index that would link to the files details. The problem is that the table is so large (around 500 million rows) that the search time is very slow. I am hoping that Partitioning could be a solution to my problem.

Here is the file name index table structure:

File name (PK, string, usually contains a few words)
file size (int)
date (date)

Once a search is done a 'Like' operator will be used against all file names to obtain the most relevant search results, and then the related table with file details will be pulled up (the easy part).

I am unsure how I could use partitioning to segment the data as any search has to match against all names in any case. The user may be searching for a word that is in the middle of a file name or a combination of words within the file name.

If anyone could suggest a method of increasing performance it would be much appreciated.

Thank you.
