The removeStopWords parameter removes common, low-value words from queries to improve relevance. This is useful for natural language queries where words like “what”, “is”, or “the” do not contribute to the search intent. For example, a query like "what is a record" becomes "record", which helps avoid irrelevant matches. To learn more, see Removing stop words.

​
Options

​
true
Removes stop words for all supported languages. If queryLanguages is set, only those languages are affected.
​
false
No stop words will be removed from the query.
​
list<enum<string>>
Languages (as ISO 639-1 codes) for which to remove stopwords. Overrides any language(s) set in queryLanguages. See the list of supported languages.

​
Usage

  • This setting is used in conjunction with queryLanguages.
  • Works best for full-sentence or voice queries. For keyword searches, it is usually best to leave this off.
  • Stop words are not removed from words interpreted as prefixes. To control prefix behavior, use queryType.
