"Many" things are strange

Don't hate me for the pun!

"Many" can mean (as far as the search is concerned) "large group of objects" or "large group of people" or "large group of animals". All reasonable.

If I search for "something AND many", e.g. turnip AND many the "many" keyword is ignored.
If I search for "turnip" I get 1927 files.
If I search for "turnip AND many" I get 1927 files.
If I search for "turnip" then later add "many" from the left-hand search box I still get 1927 files.
If I search for "many" I get 179192 files.
If I then add "turnip" from the left-hand search box I get 1927 files.

If I use "large group of objects" rather than "many" I get a much more likely set of 78 files that are mostly pictures of lots of turnips.

On the other hand, "few" can similarly mean "small group of objects" or "small group of people" or "small group of animals".

If I search for "something AND few", e.g. turnip AND few the "few" keyword works as expected.

So it seems to be a problem specifically with "many".

Hmmmm. This is odd. Lemme do some investigating and get back to you.
