queryOptions
Option Type Description
awaitData bool Block rather than returning no data. After a period, time out. Useful for tailable cursor

modifiers array Meta operators modifying the output or behavior of a query
noCursorTimeout bool Do not timeout a cursor that has been idle for more then 10minutes
oplogReplay bool Internal MongoDB Server flag
partial bool Get partial results from mongos if some shards are down (instead of throwing an error)
projection array|object Specifies the fields to return using booleans or projection operators
readConcern MongoDB\Driver\ReadConcern Level of isolation for querying replica sets and replica set shards. This option requires the WiredTiger storage engine and MongoDB 3.2 or later.
skip integer The number of documents to skip before returning
slaveOk bool Allow query of replica set secondaries
sort array|object The order in which to return matching documents
tailable bool Cursor will not be closed when the last data is retrieved. You can resume this cursor later
