This is proposed and justified at [[Wikipedia:Village_pump_(proposals)#RFC:_Proposal_that_basic_search_should_include_category_search]].  In brief: Including category search in basic search (by default) would help reduce the number of near-duplicate articles with different names. Few people seem to know how to do an advanced search that includes category names.
Related suggestion: When an editor adds a link to "ABC" then at present Wikipedia tells the editor, "There isn't an article called "ABC", do you want to create one (if such an article doesn't exist). Surely it would be better if the message were, "There isn't an article called "ABC", but there is a category "ABC". Do you want to **view the category "ABC"** (this would link to the category search results page) or create a new article "ABC"? 

(I will post this under the Lucene search extension as well).
