-----------------------------------------
GitHub user nickva opened a pull request:
https://github.com/apache/couchdb-couch/pull/162
Implement Mango selectors for change feeds
API is modeled after _doc_ids filter for change feeds.
User POSTs to {db}/_changes with `filter=_selector`.
Document body should have a "selector" field, with
a Mango selector object as value.
For example:
```
http://.../d1/_changes?filter=_selector
{
"selector": {"z" : {"$gte" : 1} }
}
```
In case "selector" is missing or its value is not a
JSON object, a 400 error is returned with a
corresponding error message. For example:
```
{
"error": "bad_request",
"reason": "Selector error: 42, expected an object"
}
```
In case "selector" object cannot be validated as a
Mango selector, a 400 error is returned with a validation
error as "reason".
