You probably just need to escape the backslashes with a backslash -
otherwise the query parser will treat your backslashes as escapes and remove
them. This is not unlike placing a regex in a Java string literal.

Subject: regex constructs allowed in queries
Hi, I can't find anywhere good documentation of what syntax is allowed in
Solr 4.4 regular expression searches. I can get regexes to work, but the
same search with a predefined character class (like \s) or a word boundary
matcher (\b) returns nothing. I am searching an untokenized field and using
a plain space (' ') instead of '\s' works fine.
Is there a different escape syntax for regex constructs using a backslash?
Is the regex support just incomplete? Or am I hitting some sort of bug?
Thanks,
Hugh=
