Text Search Parameters
You can configure Vertica for text search using these parameters.
Parameters | Description |
---|---|
TextIndexMaxTokenLength |
Controls the maximum size of a token in a text index. If the parameter is set to a value greater than 65000 characters, then the tokenizer truncates the token at 65000 characters. You should avoid setting this parameter near 65000 (the maximum value). Doing so can result in a significant decrease in performance. For optimal performance, the parameter should be set to the maximum token value of your tokenizer. Default Value: 128 characters Example: ALTER DATABASE database_name SET PARAMETER TextIndexMaxTokenLength=760; |
