Hi, So the good news: most of the faceting tests now pass with ES.
I rebased the patch onto master. https://github.com/gsmet/hibernate-search/commits/elastic-facet2 and for now only one commit: https://github.com/gsmet/hibernate-search/commit/657ecfe684e6b4e952d11274523a4c5683e0c7eb It's not a PR yet as it's not feature complete and there are still (a few) tests failing. General infrastructure ================ - I introduced a JsonBuilder to make the gson API chainable: I think it's more readable this way. I haven't updated everything to use it (especially the Lucene Query -> Json part is not ported yet). Should I continue with it? Please, please, say yes :). - All the API is now based on JsonObject so you don't have to play with String -> Json -> String -> Json manipulation ---> would appreciate feedback on these 2 changes so that I can make everything consistent - I introduced a ToElasticSearch class which translates Lucene/HSearch objects to Json. I moved the existing query translator there. - I'm not sure building the exact same document we build for Lucene is the way to go. I'm wondering if we should have a distinct document builder for ES. I'll see how it works for facets not being fields. - I made a few fixes here and there: especially the indexing didn't support multiple values per field. I made something complicated, maybe we could just index a JsonArray even for single values? see https://github.com/gsmet/hibernate-search/commit/cb88b5790996442e137fab4aec330be04dfef587#diff-e832854d983fba756218944587fd5c57R234 Faceting ======= - The querying/extraction should be OK - ES doesn't support range bounds inclusion/exclusion for range faceting so I used the query faceting to build the range faceting - I have to work on the mapping as having multiple facets on the same field is not supported yet: currently I use the indexed field to build the facets, not specific fields - I have some additional work to do on indexing related to the above matter Various issues =========== - A few tests don't pass: . ElasticSearch returns facets results even if the field doesn't exist: not sure we can do anything about that . A test in the WebShopTest is failing as I don't support yet faceting based on a non existing field . CollectionUpdateEventTest is failing: this one is weird - I had to work around an issue with the EsDateBridge and faceting (marked as XXX in DocumentBuilderIndexedEntity): Dates are considered to be Long and for ES, we want them to be Strings. Would appreciate a comment on that. Comments and thoughts appreciated. -- Guillaume _______________________________________________ hibernate-dev mailing list hibernate-dev@lists.jboss.org https://lists.jboss.org/mailman/listinfo/hibernate-dev
