If the contents of the field are "Ergo Roller" and you search for
"Roller Ergo", it will not be found. Try to write a sql query where
this would work.
Of course if you search for "Roller" or "Ergo" on their own, you will
find the record.

You could break down the incoming search terms in perl and use a complex
sql "or" query to "tokenize" the search, but if this is something you
really need to work in an efficient manner, and will have many queries
running, you may want to create a special indexed text field and insert
the potential strings you want to find... ie
code desc ext_search
123 Ergo Roller Ergo Roller Roller Ergo
Roller-Ergo Ergonomic Rollers
and use either sub string or a sql query
select * from products where ext_search like '%$searchterm%'
after properly filtering the incoming $searchterm

It is may or may not be related to what you are trying to do, but the
search itself will not work.
