Hi, I have one custom Solr plugin that uses MoreLikeThis class. AFAIK, MoreLikeThis handler does not support distributed mode and the issue is still open for that - https://issues.apache.org/jira/browse/SOLR-5480.
However, I saw that there is some possibility to use CloudMLTQParser to work around above issue. CloudMLTQParser claims to work in distributed mode too - https://issues.apache.org/jira/browse/SOLR-6248. When I took a look at the code though, https://github.com/apache/lucene-solr/blob/2d690885e554dda7b4b4e0f46f2bd9cacdb32df6/solr/core/src/java/org/apache/solr/search/mlt/CloudMLTQParser.java , it seems like that for the document for which we are finding out related documents, that document is getting fetched now with real-time get request handler. core.getRequestHandler("/get").handleRequest(request, rsp); This is good because now that document will get fetched from any shard existing in cloud wherever that document exists. However, the part where the relevant related documents are supposed to be fetched it still uses the same old sort of code. e.g. MoreLikeThis mlt = new MoreLikeThis(req.getSearcher(). getIndexReader()); Isn't getSearcher bound to only the particular shard and AFAIK it does not work across shards in cloud? So how then, CloudMLTQParser works in SolrCloud mode? Does it even work?
