return BSON regular expressions as BSONRegExp instances.
the serializer will check if keys are valid.
Comment to apply to the operation.
In server versions pre-4.4, 'comment' must be string. A server error will be thrown if any other type is provided.
In server versions 4.4 and above, 'comment' can be any valid BSON type.
(MongoDB 4.4. or higher) Specifies how many data-bearing members of a replica set, including the primary, must complete the index builds successfully before the primary marks the indexes as ready. This option accepts the same values for the "w" field in a write concern plus "votingMembers", which indicates all voting data-bearing nodes.
Enable utf8 validation when deserializing BSON documents. Defaults to true.
Allows you to expire data on indexes applied to a data (MongoDB 2.2 or higher)
Specifies the verbosity mode for the explain output.
allow to specify if there what fields we wish to return as unserialized raw buffer.
Specifies that the index should exist on the target collection but should not be used by the query planner when executing operations. (MongoDB 4.4 or higher)
serialize will not emit undefined fields (default:true)
For geospatial indexes set the high bound for the co-ordinates.
For geospatial indexes set the lower bound for the co-ordinates.
Override the autogenerated index name (useful if the resulting name is larger than 128 bytes)
Creates a partial index based on the given filter object (MongoDB 3.2 or higher)
when deserializing a Binary will return it as a node.js Buffer instance.
when deserializing a Long will fit it into a Number if it's smaller than 53 bits
when deserializing will promote BSON values to their Node.js closest equivalent types.
Enabling the raw option will return a Node.js Buffer which is allocated using allocUnsafe API. See this section from the Node.js Docs here for more detail about what "unsafe" refers to in this context. If you need to maintain your own editable clone of the bytes returned for an extended life time of the process, it is recommended you allocate your own buffer and clone the contents:
Specify a read concern and level for the collection. (only MongoDB 3.2 or higher supported)
The preferred read preference (ReadPreference.primary, ReadPreference.primary_preferred, ReadPreference.secondary, ReadPreference.secondary_preferred, ReadPreference.nearest).
Should retry failed writes
Specify ClientSession for this command
Creates a sparse index.
Allows users to configure the storage engine on a per-index basis when creating an index. (MongoDB 3.0 or higher)
Creates an unique index.
Specifies the index version number, either 0 or 1.
Write Concern as an object
Generated using TypeDoc
Creates the index in the background, yielding whenever possible.
