Auto Synonyms
Use the Auto Synonyms feature in AddSearch to automatically identify search queries that return no results ("no-hit" keywords) and suggest contextually relevant synonyms. This helps improve search result accuracy and reduces manual synonym management.
How to Enable Auto Synonyms
- Log in to your AddSearch account.
- Navigate to Manage results and select Synonyms.
- Toggle on Automatically add new synonyms to activate Auto Synonyms.

Reviewing and Managing Auto Synonyms
After enabling, the system detects no-hit keywords from user searches and automatically suggests synonyms.
- To review suggestions, go to the Synonyms page.
- Review the suggested synonyms linked to no-hit keywords.
- Remove any irrelevant synonyms manually if needed.

Set the Language for Synonym Generation
By default, Auto Synonyms uses auto-detected language to generate synonyms. To specify a language:
-
Click the Language Configuration button in the Synonyms section.

-
Select one language from the drop-down list.

-
Click Save to apply the selection.

Note: Only one language can be set per search index. For supporting multiple languages, create separate indices for each language.
