Filter items which array contains any of given values

Question

I have a set of documents like

{     tags:['a','b','c']     // ... a bunch properties } 

As stated in the title: Is there a way to filter all documents containing any of given tags using Nest ?

For instance, the record above would match ['c','d']

Or should I build multiple "OR"s manually ?

Answer 1

elasticsearch 2.0.1:

There's also terms query which should save you some work. Here example from docs:

{   "terms" : {       "tags" : [ "blue", "pill" ],       "minimum_should_match" : 1   } } 

Under hood it constructs boolean should. So it's basically the same thing as above but shorter.

There's also a corresponding terms filter.

So to summarize your query could look like this:

{   "filtered": {     "query": {       "match": { "title": "hello world" }     },     "filter": {       "terms": {         "tags": ["c", "d"]       }     }   } } 

With greater number of tags this could make quite a difference in length.
