hello, I have plenty of docs and each docs maybe connected to many user-defined tags.I have used solr-cloud, and use JOIN to do this kind of job,and recently i know solr-cloud does not support distributed search.AND so this is a big problem so far.AND the decouple is quite impossible,because docs and user-defined tags are so huge,and many search is always searched on these two fields.ANY good idea to deal with this problem?
