When using Dismax, Solr 5.1 tries to compare the entire field to the search string, instead of only using keywords

Hi all. Sorry about the title, but I don't know how to be more explicit than that. I am updating a Solr 1.4 install to Solr 5.1. I went through all the changes, updated my schema.xml, etc. Everything works (I re-indexed instead of migrating the existing one). I can search for documents, no problem

Hi Rob, Reading your use case I can not understand why the Query Time join is not a fit for you ! The documents returned by the Query Time Join will be from core1, so faceting and filter querying that core, would definitely be possible ! I can not see your problem honestly ! Cheers 2015-06-04 1:4

Solr Atomic Updates by Query

Hi! I have one more question about atomic updates in Solr (Solr 4.4.0). Is it posible to generate atomic update by query? I mean I want to update those documents in which IDs contain some string. For example, index has: Doc1, id="123|a,b" Doc2, id="123|a,c" Doc3, id="345|a,b" Doc4, id="345|a,c,d".
