: When performing a facet query where part of the value portion has a : special character (a minus sign in this case), the query returns zero : results unless I put a wildcard (*) at the end.
check your analysis configuration for this fieldtype, in particular look at what debugQuery produces for your parsed query, and look at what analysis.jsp says it will do at query time with the input string "pds-comp.domain" ... because it sounds like you have a disconnect between how the text is indexed and how it is searched. adding a * to your input query forces it to make a WildcardQuery which doesn't use analysis, so you get a match on the literal token. in short: i suspect your problem has nothing to do with query string escaping, and everything to do with field tokenization. -Hoss
