| Property | Description |
|---|---|
| behaviors (opens new window) | yii\base\Behavior (opens new window) – List of behaviors attached to this component. |
| maxPostgresKeywordLength | integer (opens new window) – Because the keywords column in the search index table is a B-TREE index on Postgres, you can get an "index row size exceeds maximum for index" error with a lot of data. |
| minFullTextWordLength | integer (opens new window), null (opens new window) – The minimum word length that keywords must be in order to use a full-text search (MySQL only). |
| useFullText | boolean (opens new window) – Whether fulltext searches should be used ever. |
# maxPostgresKeywordLength

for index" error with a lot of data. This value is a hard limit to
truncate search index data for a single row in Postgres.
