Fields
name

string

A field name of the form projects/{project_id}/databases/{database_id}/collectionGroups/{collectionId}/fields/{fieldPath}

A field path may be a simple field name, e.g. address or a path to fields within mapValue , e.g. address.city, or a special field path. The only valid special field is *, which represents any field.

Field paths may be quoted using (backtick). The only character that needs to be escaped within a quoted field path is the backtick character itself, escaped using a backslash. Special characters in field paths that must be quoted include:*,., ``` (backtick),[,]`, as well as any ascii symbolic characters.

Examples: (Note: Comments here are written in markdown syntax, so there is an additional layer of backticks to represent a code block) \address.city`represents a field namedaddress.city, not the map key cityin the fieldaddress. `*`represents a field named*`, not any field.

A special Field contains the default indexing settings for all fields. This field's resource name is: projects/{project_id}/databases/{database_id}/collectionGroups/__default__/fields/* Indexes defined on this Field will be applied to all fields which do not have their own Field index configuration.
