-------------------------------------
Summary: Mango: should be able to index *within* arrays
Key: COUCHDB-2867
URL: https://issues.apache.org/jira/browse/COUCHDB-2867
Project: CouchDB
Issue Type: Improvement
Components: Mango
Reporter: Nolan Lawson
If you have a document like:
{code:javascript}
{
"_id": "foo",
"tags": ["a", "b", "c"]
}
{code}
...then you should be able to run queries that find e.g. all documents with "a"
as a tag, and it should be *indexed*. Currently there doesn't seem to be any
way to do this except as an in-memory selector, which is a real bummer, because
it's a super common use case. (Tags, categories, labels, etc.)
Originally I thought this was how {{$elemMatch}} worked, and I was surprised to
learn that that's not the case.
