No manual advanced search when default search-settings are changed

[Markus]

When searching for something that includes an advanced search command (rating, order), the system still appends its own command when it was changed from the default in the settings.

yuri rating:safe --> /post.json?tags=yuri+rating%3Asafe%20rating:explicit&limit=5.000000&page=1
