Split out from Issue2550648 (Should be possible to search for matching 
several keywords (keyword1 AND keyword2)):

| BTW: I think the new features deserve some entry in doc/upgrading.txt
| for existing tracker installations...

When we're at it: It would be nice to have a small regression test for
this, too. I've recently re-factored the sql generation (for
implementing filter_iter) and was unsure if I had broken some of the new
features.

If you can give me a search-URL that uses (if possible *all*) of the new
search features I'll volunteer to put this into (one or several) tests.

Not right now. Just use the javascript on a new tracker to get one.
Thanks for helping!

@schlatterbeck:
Examples, hope this helps. :)
Basics:
1) first AND second keyword:
  /demo/issue?%40action=search&keyword=1,2,-3
2) NOT first keyword
  /demo/issue?%40action=search&keyword=1,-2
3) second OR third keyword:
  /demo/issue?%40action=search&keyword=2,3,-4
  should be equivalent to the old implicit OR behaviour
  /demo/issue?%40action=search&keyword=2,3

More involved:
4) testing together: ( first AND NOT third ) OR fourth keywords
  /demo/issue?%40action=search&keyword=1,3,-2,-3,4,-4
