Thanks Darren, The problem with that is that it may not return one document per id, which is what I need. IE, I could give 100 ids in that OR query and retrieve 100 documents, all containing just 1 of the IDs.

I think I understand. What's impossible about this? If you have a single field name called <id> that is multivalued then you can retrieved the documents with something like: id:1 OR id:2 OR id:56 ... id:100 then add limit 100. There's probably a more succinct way to do this, but I'll leave that to the experts. If you also only want the documents within a certain time, then you also create a <time> field and use a conjunction (id:0 ...) AND time:NOW-1H or something similar to this. Check the query syntax wiki for specifics. Darren > Hey everyone, > > I've recently been given a requirement that is giving me some trouble.
