Defining Google BigQuery Table Indexes

The following properties are applicable to a Google BigQuery Index object.

Tab	Property	Description	Additional Information
	Physical Name	Specifies the name of the search index
	Type	Specifies whether the index type is PK, Search, or Vector index	PK stands for primary key index. You can create multiple search or vector indexes for each table in a Google BigQuery database. However, you can generate only one search index and one vector index at a time.
	If Not Exists	Specifies that if the index already exists, no exception is thrown, and no action happens
	Physical Only	Specifies whether the index appears in physical models only
	Generate	Specifies whether a DDL statement is generated for the dataset during forward engineering
General	Index Members	Specifies the list of eligible columns to create primary key or search index	Available for search index only if All Columns is not selected
	Type	Specifies the primary key index type	Available only when the index type is set to PK
	All Columns	Specifies whether the index is created on all columns of the table	Available when the Type is set to Search Search Indexes are created only on columns of the types STRING and JSON, or contain a STRING or JSON field in them.
	Analyzer	Specifies controls of the text analyzer and how data is tokenized for searching and indexing	Available when the Type is set to Search
	Data Types	Specifies the data types to use when a search index is created	Available when the Type is set to Search
	Distance Type	Specifies to use a default distance type when performing a vector search	Available when the Type is set to Vector Valid values are EUCLIDEAN, COSINE, and DOT_PRODUCT
	Index Type	Specifies the algorithm that is used to build the vector index	Available when the Type is set to Vector
	Ivf Option	Specifies the algorithm to build the index as an inverted file index	Available when the Type is set to Vector
	Tree Ah Option	Specifies the algorithm to build the index as a tree-quantization based index	Available when the Type is set to Vector
	Use Replace Syntax	Specifies whether to use a replace syntax	Available when the Type is set to Vector
Vector Index	Stored Columns	Specifies the vector indexes for the stored columns	This tab is applicable only when the index Type is set to Vector
Comments		Specifies comments about the search index
