OpenSearch:Manage dictionaries

Overview

OpenSearch provides built-in dictionaries to simplify and enhance query analysis. You can also create custom intervention dictionaries to supplement the built-in ones without manually entering all required information. The built-in dictionaries include Synonym, Spelling Correction, Stop Word, and Term Weight, as shown in the following figure.

Usage notes

• You cannot configure or delete the built-in dictionaries.

• By default, when you create a custom query analysis rule, Built-in Dictionary is selected to enrich query statements. You cannot clear Built-in Dictionary.

• If you specify a custom intervention dictionary when you create a custom query analysis rule, the built-in dictionaries and the custom intervention dictionary are used in combination. If an entry in the built-in dictionaries conflicts with an entry in the custom intervention dictionary, the entry in the custom intervention dictionary prevails.
