Number of bits used to store numerical values. For unsigned numerical fields, the possible values are [0; 2^N - 1], and the field values are stored on N bits. For signed fields (signed integer and double), the possible values are [-2^N, 2^N - 1], and the field values are stored on (N+1) bits.

Delta ref encode multivalued values.

Storing multivalued RAM-based values in an increasing order consumes less RAM. This must be disabled to use some advanced multivalued virtual functions.

A value field must be RAM-based to perform synthesis efficiently.

The name of the field. The name of a field can only contain lower-case characters, numbers and underscore. [a-z0-9_]+

Allows users to query on this field (using a prefix handler).

Allows the content of this field to be retrieved at query time and displayed in the search results.

Is this index field config managed by a data model? @enum{null,auto,customized}. If null, this is not related to a data model. If "auto", this is auto-generated by a data model. If "customized", this was auto-generated by a data model and then customized.

If dataModelState is "auto" or customized", you will find here the name of the DataModelClass that generated this field config.

If dataModelState is "auto" or customized", you will find here the name of the DataModelProperty that generated this field config.

If dataModelState is "customized", you will find here the original object generated by the data model. Use this to easily revert to "auto" state from "customized".

Configuration of the inverted lists encoder. If no configuration is specified, a Rice encoder is used.
