API Reference / API Parameters

Scope

Each parameter in this page has a scope. Scope signifies the timing of when the parameter takes effect.

There are three scopes:

  • settings: They can only be used in the setSettings method.
  • search: They can only be used in the search method.
  • settings search: The setting can be used in the setSettings method and be overridden in the search method.

All parameters used in setSettings are called "Index Settings". They change the index during indexing time; they impact all searches. All parameters used in search are called "Query Parameters". Their effect is temporary, impacting only the current query.

While many query parameters override an index setting, some add new functionality. Some parameters can be used at both indexing and query time. See more here.
