Alias for multiple indexes, why can't I use /indexname/doctype/docno?

[ankh]

We have an alias combining multiple indexes. Searching across the indexes via the alias and the _search endpoint is fine.

However, when referring to a document by its ID as a URI:

curl http://the-node:9200/the-alias/doc/123

we get the error:

"Alias [the-alias] has more than one indices associated with it [[the-index1, the-index2]], can't execute a single index op"

I can understand why you can't index via a multi-index alias, but why can't you get a document via a URI?

How does it know what document to get if there are multiple that match?

[ankh]

That makes sense. The way we're loading the indexes, the ids in one index will not overlap with ids in other indexes, so I didn't consider that.

Whereas, I guess, a search for a particular id will just return multiple documents if the same id was in multiple indexes.

Thanks!

Yeo GET isn't smart enough to reconcile or provide priority or anything, it's a basic operation designed for a single document
