问题 I have millions of documents in my Solr index. Only a thousand of those documents have field A, whose schema I want to change.

问题 I'm trying to use a synonym filter to search for a phrase. peter=> spider man, spiderman, Mary Jane, ..... I use the default configuration. When I put these synonyms into synonym.txt and restart Solr it seems to work only partially: It starts to search for "spider" , "man" , "spiderman" , "Mary" and "Jane" but what I want to search for are the meaningful combinations - like "spider man" , "Mary Jane" and "spiderman" . 回答1: Yes sadly this is a well known problem due to how the Solr query

问题 I've been attempting to do the equivalent of an UPSERT (insert or update if already exists) in solr.
