I just did a search for "newspapers of the United States" on the English Wikipedia. The article "Newspapers in the United States" exists, and should have been the first or second result, but isn't even on the first page:
I had to make a redirect so people can find the correct article. It seems the results are poorly ranked, I assume a tuning issue because this is a chronic problem across many search that feel like that should have given much better results. I recently optimized Solr queries for better ranking for an education search engine; I might be of some technical assistance if someone wants to point me in the right direction for experimenting with tweaks. I have a hunch whatever query is being run just needs to put more weight on article titles, and do the equivalent of what Solr calls Phrase Fields.
