The ignorePlurals parameter controls whether Algolia treats singular, plural, and other inflected forms as equivalent.
For example, "car" matches "cars" and "child" matches "children". For more information, see Ignoring plurals and other forms.

​
Options

​
true
Treat plural and inflected forms as equivalent for all supported languages. If queryLanguages is set, only those languages are affected.
​
false
Plurals and other declensions will be treated as separate words.
​
list<enum<string>>
List of languages (as ISO 639-1 codes) for which plural and inflected forms should be treated as equivalent. Overrides any language(s) set in queryLanguages. See the list of supported languages.

​
Usage

  • You should only turn on ignorePlurals for languages used in your data.
  • If ignorePlurals is set to true without specifying queryLanguages, Algolia enables plural normalization for all supported languages. This may lead to unexpected matches. For example, the French word "chair" (meaning “flesh”) may match "chairs" in English.

​
Examples

​
Set default query language and ignore plurals

Current API clients

var response = await client.SetSettingsAsync(
  "ALGOLIA_INDEX_NAME",
  new IndexSettings
  {
    QueryLanguages = new List<SupportedLanguage> { Enum.Parse<SupportedLanguage>("Es") },
    IgnorePlurals = new IgnorePlurals(true),
  }
);

IndexSettings settings = new IndexSettings();
settings.QueryLanguages = new List { "es" };
settings.IgnorePlurals = true;

index.SetSettings(settings);

​
Override query language in search request

Current API clients

var response = await client.SearchSingleIndexAsync<Hit>(
  "ALGOLIA_INDEX_NAME",
  new SearchParams(
    new SearchParamsObject
    {
      Query = "query",
      IgnorePlurals = new IgnorePlurals(
        new List<SupportedLanguage>
        {
          Enum.Parse<SupportedLanguage>("Ca"),
          Enum.Parse<SupportedLanguage>("Es"),
        }
      ),
    }
  )
);

index.Search(new Query("")
{
    IgnorePlurals = new List { "ca", "es"}
});
