Searches with force=1&sort_name don't support spaces in the sort_name parameter
For example if I want to return all contacts with first name
Jar Jar but not
Jar Joe I can't search for
sort_name=Jar+Jar. It just ignores the parameter completely and returns all contacts.
I don't have a stake in this, and not sure how important it is to anyone, just noting it as it has come up in testing of the force=1 searches.
