I have an index that contains two user's data. I want to provide each user the ability to query the index, but to only see those rows of data that contain the field 'user=their\_username'. Can I do this with Shield or some other [elastic.co](http://elastic.co) configuration mechanism? If so, how would I go about it? Ideally each user would have to login with a password I assign them first. Thank you. ---

Shield can totally do this - [https://www.elastic.co/guide/en/shield/current/setting-up-field-and-document-level-security.html#document-level-security](https://www.elastic.co/guide/en/shield/current/setting-up-field-and-document-level-security.html#document-level-security) ---
