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
