It's a project I have for a long time. I wanted to have an intern this year to work on this and a few other search features I have in mind for HSearch. It becomes more and more obvious I won't have the time to work on this myself but I wanted to be able to play with this idea anyway. That said, I haven't found anyone so far... Background: I worked a lot with Apache Solr before switching to Java and Hibernate Search. Apache Solr has a (e)dismax query parser which IMHO is very very useful. The principle is the following: - you have a text to search typically: hibernate search is great - you tell him to search it in title^5 content^2 - you tell him that starting with 3 words, it can ignore 1 (mm parameter = minimum should match) and it builds a search query doing exactly that. The edismax query parser is quite advanced, sometimes a little buggy but it's usually what I want when I implement a search engine. The only thing we have added so far in our Solr powered application is the fact that we also support search in fields with a fuzzy query. So you can have: title~0.8^5 content~0.8^2 (it's not perfect as fuzzy queries are weird but it does the job and you use it only if you want it). Reference is here: https://wiki.apache.org/solr/ExtendedDisMax The most interesting parameters to understand the principle are qf and mm, but the others are quite useful too. Happy to discuss this subject. -- Guillaume _______________________________________________ hibernate-dev mailing list hibernate-dev@lists.jboss.org https://lists.jboss.org/mailman/listinfo/hibernate-dev
