: My thought was, that I could separate indexes. So for the facet queries : where I don't need : fulltext search (so also no indexed fulltext field) I can use a completely : new setup of a : sharded Solr which doesn't include the indexed fulltext, so the index is : kept small containing : just the few fields I have. : : And for the fulltext queries I have the current Solr configuration which : includes as mentioned : above all the fields incl. the index fulltext field. : : Is this a normal way of handling these requirements. That there are : different kind of : Solr configurations for the different needs? Because the huge redundancy
It's definitley doable -- one thing i'm not clear on is why, if your "faceting" queries don't care about the full text, you would need to leave those small fields in your "full index" ... is your plan to do "faceting" and drill down using the smaller index, but then display docs resulting from those queries by using the same "fq" params when querying the "full index" ? if so then it should work, if not -- you may not need those fields in that index. In general there is nothing wrong with having multiple indexes to solve multiple usecases -- an index is usually an inverted denormalization of some structured source data designed for fast queries/retrieval. If there are multiple distinct ways you want to query/retrieve data that don't lend themselves to the same denormalization, there's nothing wrong with multiple denormalizations. Something else to consider is an approach i've used many times: having a single index, but using special purpose replicas. You can have a master index that you update at the rate of change, one set of slaves that are used for one type of query pattern (faceting on X, Y, and Z for example) and a differnet set of slaves that are used for a different query pattern (faceting on A, B, and C) so each set of slaves gets a higher cahce hit rate then if the queries were randomized across all machines -Hoss
