Re: [searchisko-dev] How to represent this as a query

Hi Pete, You can use: accounts.username:pmuir AND accounts.domain:"vimeo.com" but there are some gotchas: Imagine the following document: { displayName: "Pere Muir", accounts: [ {username: "pmuir", domain: "vimeo.com"}, {username: "petemuir", domain: "youtube.com"} ] } When this is indexed then it is transformed to the following document (at Lucene level): { displayName: "Pete Muir", accounts.username: ["pmuir","petemuir"], accounts.domain: ["vimeo.com","youtube.com"] } Both 'accounts.username' and 'accounts.domain' is name for a field name - it just contains a dot, there is no notion of "nestedness" in it at Lucene level. At this point you can notice that we lost connection between username and domain. We do not know which username belong to which domain. This means we can have query: accounts.username:petemuir AND accounts.domain:"vimeo.com" and it would result into the same document in spite of the fact that was no account for vimeo.com having username petemuir. So the question is if this is a problem for you now or not. I can imagine that you might be fine with how it works for now - it depends what you exactly need to retrieve from the DCP. However, going forward we can expose a query that would honour the "nestedness" because Elasticsearch provides it [1]. Let me know if you have more questions.
