: With an implicit collection, is it legal to index the same document : (same unique ID) in 2 different shards? I know, it kind of defeats the : purpose of having a unique ID...
Each doc (defined by uniqueKey) must exist in one and only one shard ... when this constraint is violated, you'll start to get undefined behavior at request time. : So my actual question is the following: if my search query guaranties : there will be no duplicate matches, is my search result going to be : consistent? That's assuming it's "legal" to have duplicates across : shards from an indexation point of view. the answer is "probably" -- but that's just an implementation detail at the moment, it does it's best to account for weird situations like this. but nothing in the architecture / design garuntees that for you in the future. -Hoss http://www.lucidworks.com/
