Simple question really - the default search-method here is OR - ie a search for "apples oranges" will show posts that have either apples or oranges or both. I want to show only posts that have both apples and oranges in them.
I tried "apples and oranges" but that returns the same as "apples oranges".
Surely there's a way to do exclusive search sets without resorting to the google-search?
Using a + before a search term means it must be included in the results, so the following produces a boolean AND search:
+apples +oranges
(this also works on quoted phrases, optional ninja options, etc.)
Why don't we do AND by default?
Well, we use OR searches by default and sort by relevance...so effectively you see AND results before OR results in the results that come up. Compare the results above to the OR version you get by default, see how the first results are the same? That's because something with both terms is simply more relevant than anything that has just one. So effectively (at least on the relevance sort), AND is a subset of OR, and it'd just be cutting the result list off at whatever the AND endpoint is...we'd rather give you all the relevant results and stick the stuff that may not be as matchy at the end.
