Re: Best way to retrieve 20 specific documents
If you are in Solr 4 you could use realtime get and list the ids that you need. For example: http://host:port/solr/mycore/get?ids=my_id_1,my_id_2...

Re: Best way to retrieve 20 specific documents
In fact, you shouldn't need OR: id:(123 456 789) will default to OR.

Re: Best way to retrieve 20 specific documents
