AFAICS from the changelog of each version, autosuggest is still a vast work in progress in Lucene/Solr. > Back to wildcard.

In theory, yes. But for the tokenization, we use WhitespaceTokenizer and WordDelimiterFilter which generates new tokens (for example, depending on the options you use, you can index wi-fi as wi and fi, wi-fi and wifi). The problem of this particular filter is also that we put it after the ASCIIFoldingFilter because we want the input to be as clean as possible but before the LowerCaseFilter as WordDelimiterFilter can do its magic on case change too. If you separate normalizer from tokenizer, I don't think it's going to be easy to order them adequately. _______________________________________________ hibernate-dev mailing list hibernate-dev@lists.jboss.org https://lists.jboss.org/mailman/listinfo/hibernate-dev
