title: Elastic search - search query to match any one value for a particular key
body: <p>I am new to ES querying. I am try to get results based on a key that can match any value rather than one particular value. For example: key <code>foo</code> can be one among <code>bar, baz</code>. I tried this with arrays and should but ended up with wrong results or exception. What will be the correct syntax for OR case in ES. I am using ES 5.6.*</p>
