Issue Description
Build a parse query that uses $relatedTo and count, in order to get results and total count.
Parse uses the "Limit" parameter value in order to limit the $relatedTo query, this causes a incorrect count value to be returned.
Steps to reproduce
await Parse.Query.fromJSON('ExampleClass',
{
"limit":15,
"skip:"0",
"where": {
"$relatedTo": {
"object": {
"__type": "Pointer",
"className": "RelatedClass",
"objectId": "someObjectId"
},
"key": "examples"
},
}
})
Actual Outcome
result = depends on order desc or asc, if valid document is in range (0-15) it will show, but if not it will not.
count = returns lower count than actual count of valid documents (14 when there are 33 for example)
Expected Outcome
result = should return all documents that match upto limit so paging can work properly.
count = should return total count of all matching documents, regardless of limit.
