Modify search engine

[mdxprograms]

I have an issue with the Mantis search functionality.
When I enter a search such as "please remove" I need to get the results of both words separately.
I have added a function to search the phrase when quotes are surrounding the search string, but I need the search to search for both words when quotes are not included.
I am guessing I need to change the database call to accept an array value?
I have tried to add the values into an array but it will not pass.

Is there something I am missing that is super easy?

I'm interested in improved searching capabilities too.
