Search Enhancements -- consolidated ticket

[Denis-de-Bernardy]

Closing the following as dups, pending "the big search overhaul" that may never come:

• #5149 -- search everywhere (with committed patch)
• #9230 -- search in post and pages and both
• #5525 -- also search for posts with search query as terms (tags, cats, ...)
• #5054 -- allow to negate keyword on search
• #7394 -- assign greater weight to posts with search query in title
• #7647 -- search in attachment descriptions

One more: #7309 -- search in entities and unicode chars.

also #7572 -- catch spelling mistakes

I've been using WordPress for years, and I've been astonished how mediocre the internal search is, but I sort of assumed that it will be fixed eventually. But no, no change whatsoever in the internal search since 2006. I've been disappointed again and again on every update. Simple things like: 1) Returning the results in order of relevance; 2) Highlighting the matches; 3) Showing only the text snippets surrounding the matches; etc. simple things, which have become the standard for any search engine, are still not available in WordPress. Shame, real shame!
