Remove + conversion in search except for tags (#3489)

Before, every + sign was converted to a space to allow to search for
spaces. But the documentation stated that to search for space one has
to enclose the string in quotes. This has a confusing behavior when
searching for a string containing a + sign.
Now, the + conversion is kept only for the tag search since it's the
only one documented that way.

See #3454
