Re: [hibernate-dev] [Search] Elasticsearch - Thoughts about analyzers and fieldbridges
.
One catch is the QueryDSL: AFAIR there are a couple of cases in which we invoke
the analyzer directly to "preprocess" the tokens.. this either needs
to be killed,
or we invoke the ES server to do the same operation but that seems
inefficient.. we'll
see, I don't remember now for which cases we need such things and hopefully
there will be an alternative strategy when it comes to run queries on ES.
What comes to mind is
To search for multiple possible words in the same field, simply add them all in the
matching clause.
//search document with storm or lightning in their history
Query luceneQuery =
mythQB.keyword().onField("history").matching("storm
lightning").createQuery();
The More Like This implementation also applies Analyzers to create the right corpus. And
the algorithm is specific to Hibernate Search and field centric rather that Lucene
document centric implementation. Maybe Elasticsearch follows our approach too.
