naturalLanguages

Languages for which to change settings to support natural language searching

• Type: list<enum<string>>
• Default: []
• Scope: search

The naturalLanguages parameter enables behaviors optimized for natural language input—such as voice queries or full-sentence searches—rather than keyword-based input.

Setting naturalLanguages automatically changes the following parameters:

• removeStopWords and ignorePlurals are set to the specified languages.
• removeWordsIfNoResults is set to allOptional.
• The value "natural_language" is added to both:
  • ruleContexts
  • analyticsTags

Usage

• Only include languages that are present in your dataset to avoid unintended matches.
• For a list of supported language ISO codes, see Supported languages.
