Re: [hibernate-dev] Similarity approach in Hibernate Search

Each time a new Document is added to the index, the similarity relevant to that entity is looked up from the pertaining documentBuilder and set to the indexwriter: AddWorkDelegate: Similarity similarity = documentBuilder.getSimilarity(); writer.setSimilarity( similarity ); writer.addDocument( work.getDocument(), analyzer ); So the analyzer is scoped per document, the similarity is globally set on the indexwriter. Does this make sense to update the similarity for each add operation type? This is a problem as I can't use two (more) threads to add documents to the same index. Is there a good use case for which someone might need a different Similarity implementation for different entities contained in the same index? I'd like to change that to an "illegal configuration".
