"Special" characters in Tag queries

[tombatron]

When making a tag query with special (non alpha-numeric) characters, those must be escaped with a \ else you'll receive a syntax error.

Since the command builder allows a string to be provided for the query this could get tricky.

^ I built a little helper function to do this (char by char), but not for tag queries, for regular queries. Consider searching for full-text, which is found in a hash. if you pass "full-text" into the query builder, that will be interpreted as Intersect (Full and NOT Text).

I have a related issue on the RediSearch Module
