Subject Re: hierarchical faceting?

It looks like TextField is the problem.

This fixed:
    <fieldType name="text_path" class="solr.TextField"
positionIncrementGap="100">
      <analyzer type="index">
          <tokenizer class="solr.PathHierarchyTokenizerFactory"
delimiter="/"/>
      </analyzer>
      <analyzer type="query">
          <tokenizer class="solr.WhitespaceTokenizerFactory"/>
      </analyzer>
    </fieldType>

I am assuming the text_path fields won't include whitespace characters.

?q=colors:red/pink
==> Doc2   (Doc1, which has colors = red isn't included!)


Is there a tokenizer that tokenizes the string as one token?
I tried to extend Tokenizer myself  but it fails:
public class AsIsTokenizer extends Tokenizer {
    @Override
    public boolean incrementToken() throws IOException {
        return true;//or false;
    }
}
