Thread:Project:Support desk/Want to Modify Default Search Engine

Hi, My site has a mediawiki 1.20 installation and I want to add a few lines of code to omit some search terms such as "a title" (Just search for title) and "the title" (just search title). I can't seem to find the search tool files or folders. Can somebody advise?

For coding reasons, we want to to keep the default search rather than install an extension such as lucene search etc. Is this possible? Thanks.
