getter/setter pair

Specifies the index usage mode for the query. Possible string values are:

  • "INDEX_USAGE_MODE_UNSPECIFIED" : Index usage mode not specified.
  • "UNUSED" : No vector indexes were used in the vector search query. See [indexUnusedReasons] (/bigquery/docs/reference/rest/v2/Job#IndexUnusedReason) for detailed reasons.
  • "PARTIALLY_USED" : Part of the vector search query used vector indexes. See [indexUnusedReasons] (/bigquery/docs/reference/rest/v2/Job#IndexUnusedReason) for why other parts of the query did not use vector indexes.
  • "FULLY_USED" : The entire vector search query used vector indexes.
