Hi, I am working on applying parent/child types to search using Solr, and wanted to inquire about two things.
1) BlockJoin Facet Currently, there are two cores. The first core (the item core) has 16 million documents, and the second core (the product core) has 3 million documents. The product core is the parent, and the item core is the child. To apply this parent/child relationship to searches, I thought that I could use BlockJoin Facet, but because the number of documents being searched is so large, I am worried about the decrease in performance of Solr when using BlockJoin Facet. I thought it may be possible to avoid dips in performance while using BlockJoin Facet by using limit and sort, however when I tried to look up more information about this, I was unsure of if that is possible. When using BlockJoin Facet, is it not possible to use limit and sort? 2) JSON Facet API While I was researching about the above problem, I came across JSON Facet API. Is it possible to do the same thing as BlockJoin Facet with JSON Facet API? If it is possible, what is the most appropriate way to use each one? I was unable to find an official document with more detailed information about Solr's JSON Facet API, so if anyone knows of a relevant resource or reference material, I would be grateful if you could share it. I apologize for the rather open-ended question, but an answer or even a point in the right direction (an article or resource) would be greatly appreciated. Thanks, Kamu
