hi, I'm trying to use Elasticsearch as a datastore for rules (modeled as documents). The challenge is that a search returns many documents, which means many "rules" matched the query - I am trying to find a way to get Elasticsearch to rank them automagically. For example, I have four documents _id_:1 _title_: sss _team_: a _not-team_: _id_:2 _title_: sss1 _team_: a,b (multivalued fields) _not-team_: _id_:3 _title_ sss2 _team_: _not-team_:a _id_:4 _title_: sss3 _team_: _not-team_: (remember that _not-team_ means that a person is NOT in team ) Now,searching for "team:a" should return three documents 1,2,4 (note that 4 is also returned, since it does not say anything about "a" which implies a match) - but ranked with 1 \>\> 2 \>\> 4 starting from most specific to least specific. I do expect to have a validation layer in my application as well, but it would be great if this can be done at the Elasticsearch level. This would be perfect as a NoSQL like application of Elasticsearch. could someone point me in the right direction ? thanks! -sandeep ---

Would something like [teams.sh · GitHub](https://gist.github.com/12a45d7e928a1693406b) work for you?

This was very helpful - thank you very much for taking the time. I was thinking of needing to build a custom plugin for scoring, but I see that I can probably model them as boosts. This was an example of a pretty simple usecase, but the rules are expected to pretty pathological. I am just concerned about the complexity of queries. I will post back, once I have investigated this in some depth. thanks! -sandeep ---
