When a query has many results, the aggregate query to BGG can time out. For example, a search for "magic" causes the following aggregate query to be sent in GameRepository.games(forIDs:):

BGG cannot respond to this query in time, causing a gateway time out, which gets displayed as a "BoardGameGeek did not return valid XML" error.
For large queries, we should split the query into sizeable chunks to avoid this error.
When a query has many results, the aggregate query to BGG can time out. For example, a search for "magic" causes the following aggregate query to be sent in
GameRepository.games(forIDs:):BGG cannot respond to this query in time, causing a gateway time out, which gets displayed as a "BoardGameGeek did not return valid XML" error.
