Fixing Wiki Search
Your help is quite extensive, but it doesn't really fix the search problems. If someone searches for GOP pr news they will get literally nothing.
I wrote about them in my Wikimedia Search Analysis, along with some suggested fixes. At least, I think you should install the MWSearch (Lucene) extension, which an improvement. Even better, use the Sphinx Search module and most of your search problems will be easy to solve.
Best of luck,
