Re: Excluding characters from a wildcard query - More Info - Is this difficult, or am I being ignored because it's too obvious to merit an answer?

The exception SOLR raises is :

org.apache.lucene.queryParser.ParseException: Cannot parse 'vector:_*[^_]*_[^_]*_[^_]*': Encountered "]" at line 1, column 12.

Was expecting one of:
   "TO" ...
   <RANGEIN_QUOTED> ...
   <RANGEIN_GOOP> ...

Passing in a RegularExpression like "[^_]*_[^_]*" (e.g. matching anything with an underscore in the string) using some code like :

...
parameters.add("fq", "vector:[^_]*_[^_]*");
...

seems to cause problems for SOLR, I assume because of the [ or ^ character.

Can somebody please advise how to handle character exclusion in such searches?

Any help or pointers are much appreciated!

Thanks
