Provide information about attributes for an index field.
|
|
A maximum of 20 source attributes can be configured for
|
|
each index field.
|
|
|
|
:ivar default: Optional default value if the source attribute
|
|
is not specified in a document.
|
|
|
|
:ivar name: The name of the document source field to add
|
|
to this ``IndexField``.
|
|
|
|
:ivar data_function: Identifies the transformation to apply
|
|
when copying data from a source attribute.
|
|
|
|
:ivar data_map: The value is a dict with the following keys:
|
|
* cases - A dict that translates source field values
|
|
to custom values.
|
|
* default - An optional default value to use if the
|
|
source attribute is not specified in a document.
|
|
* name - the name of the document source field to add
|
|
to this ``IndexField``
|
|
:ivar data_trim_title: Trims common title words from a source
|
|
document attribute when populating an ``IndexField``.
|
|
This can be used to create an ``IndexField`` you can
|
|
use for sorting. The value is a dict with the following
|
|
fields:
|
|
* default - An optional default value.
|
|
* language - an IETF RFC 4646 language code.
