Right, you should use the MappingCharFilter from Solr; Hibernate Search can use the Solr tokenizers and filters: http://docs.jboss.org/hibernate/search/4.2/reference/en-US/html_single/#d0e462
To answer your other questions: > In short: Would it be possible to introduce Hibernate Search in the > project? (There is at least hibernate 3.0 and Jdk 1.5 on tomcat 6 with > hbm.xml files available but not with annotations). I'd suggest to use Hibernate 4.1.x, or at least Hibernate 3.6.x, so that you can make use of a Search version which wasn't built in the stone age. Hibernate 4 requires Java6 (at least). > Would it be possible to use indexed lucene search by > adding Restrictions to Hibernate Criterias? You will be able to run either Lucene (fulltext) queries, or Criteria queries: you can't mix the two APIs. There is one exception: you can use the Criteria API to define the fetching options: http://docs.jboss.org/hibernate/search/4.2/reference/en-US/html_single/#d0e5251 Regards, Sanne On 12 September 2012 15:52, Jack Krupansky <j...@basetechnology.com> wrote: > MappingCharFilter can do all of that.
