Taxonomy is ignored in search query

[anonymized_5610363]

It is not possible to make search query in given term.

For example if i do:

query_posts("taxonomy=jazyk&term=sk&s=word');

Then taxonomy and term parameters are ignored and everything containing 'word' is returned.

And it is also same if i type these parameters to url without query_posts.

Currently, is_search and is_archive are mutually exclusive, for some reason.

(In [15687]) Allow search in archive pages. Fixes #14831

Going to let it soak. Will revert if significant problems appear.
