YOU MUST FOLLOW THESE INSTRUCTIONS OR YOUR ISSUE WILL BE CLOSED.\r\n\r\nThank you for contributing to the Firebase community!\r\n\r\nHave a usage question?\r\n=======================\r\nWe get lots of those and we love helping you, but GitHub is not the best place for them and they\r\nwill be closed. Here are some resources to get help:\r\n\r\n- Start with the README: https://github.com/angular/angularfire2\r\n- Go through the Developer's Guide: https://github.com/angular/angularfire2#developer-guide\r\n- Read the full API reference: https://github.com/angular/angularfire2/blob/master/docs/api-reference.md\r\n\r\nIf the official documentation doesn't help, try asking through our officially supported channels:\r\n\r\n- Angular Google Group: https://groups.google.com/forum/#!forum/angular\r\n- Firebase Google Group: https://groups.google.com/forum/#!forum/firebase-talk\r\n- Stack Overflow: https://stackoverflow.com/questions/tagged/angular (include the firebase and angularfire tags, too!)\r\n\r\n*Please avoid double posting across multiple channels!*\r\n\r\nThink you found a bug?\r\n=======================\r\nYeah, we're definitely not perfect! Please use the bug report template below and include a minimal\r\nrepro when opening the issue.\r\n\r\nHave a feature request?\r\n========================\r\nGreat, we love hearing how we can improve our products! Remove the template below and\r\nprovide an explanation of your feature request. Provide code samples if applicable. Try to\r\nthink about what it will allow you to do that you can't do today? How will it make current\r\nworkarounds straightforward? What potential bugs and edge cases does it help to avoid?\r\n\r\n--\u003e\r\n\r\nSince I made [this comment](https://github.com/angular/angularfire2/issues/362#issuecomment-274927639) and submitted [this PR](https://github.com/angular/angularfire2/pull/821), the Firebase SDK documentation appears to have been updated and [`equalTo`](https://firebase.google.com/docs/reference/js/firebase.database.Reference#equalTo) and [`endAt`](https://firebase.google.com/docs/reference/js/firebase.database.Reference#endAt) are documented as supporting the optional `key` parameter:\r\n\r\n\u003e This argument is only allowed if ordering by child, value, or priority.\r\n\r\nAngularFire2 should also support the optional `key` parameter for `equalTo` and `endAt`.\r\n\r\nThere is a plunk [here](https://plnkr.co/edit/2IPp4KTDkk3GmNinQbmj) that demonstrates the SDK usage.","author":{"url":"https://github.com/cartant","@type":"Person","name":"cartant"},"datePublished":"2017-02-21T03:35:27.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/837/angularfire/issues/837"}
