Instance Attribute Details

#enable_dynamic_position ⇒ ::Boolean

Returns Enables dynamic position for this facet. If set to true, the position of this facet among all facets in the response is determined automatically. If dynamic facets are enabled, it is ordered together. If set to false, the position of this facet in the response is the same as in the request, and it is ranked before the facets with dynamic position enable and all dynamic facets.

For example, you may always want to have rating facet returned in the response, but it's not necessarily to always display the rating facet at the top. In that case, you can set enable_dynamic_position to true so that the position of rating facet in response is determined automatically.

Another example, assuming you have the following facets in the request:

  • "rating", enable_dynamic_position = true

  • "price", enable_dynamic_position = false

  • "brands", enable_dynamic_position = false

And also you have a dynamic facets enabled, which generates a facet gender. Then the final order of the facets in the response can be ("price", "brands", "rating", "gender") or ("price", "brands", "gender", "rating") depends on how API orders "gender" and "rating" facets. However, notice that "price" and "brands" are always ranked at first and second position because their enable_dynamic_position is false.

Returns:

  • (::Boolean) —

  #   @return [::Array<::String>]
  #     Only get facet for the given restricted values. Only supported on

  #     contains "Action > 2022". Only supported on textual fields. Maximum

  # @!attribute [rw] prefixes

  #     Only supported on textual fields. Maximum is 10.
  # @!attribute [rw] contains
  #   @return [::Array<::String>]
  #     Only get facet values that contains the given strings. For example,
  #     suppose "category" has three values "Action > 2022",
  #     "Action > 2021" and "Sci-Fi > 2022". If set "contains" to "2022", the
  #     "category" facet only contains "Action > 2022" and "Sci-Fi > 2022".
  #     Only supported on textual fields. Maximum is 10.
  # @!attribute [rw] case_insensitive
  #   @return [::Boolean]
  #     True to make facet keys case insensitive when getting faceting
  #     values with prefixes or contains; false otherwise.
  # @!attribute [rw] order_by
  #   @return [::String]
  #     The order in which documents are returned.
  #
  #     Allowed values are:

#excluded_filter_keys ⇒ ::Array<::String>

List of keys to exclude when faceting.

By default, FacetKey.key is not excluded from the filter unless it is listed in this field.

Listing a facet key in this field allows its values to appear as facet results, even when they are filtered out of search results. Using this field does not affect what search results are returned.

For example, suppose there are 100 documents with the color facet "Red" and 200 documents with the color facet "Blue". A query containing the filter "color:ANY("Red")" and having "color" as FacetKey.key would by default return only "Red" documents in the search results, and also return "Red" with count 100 as the only color facet. Although there are also blue documents available, "Blue" would not be shown as an available facet value.

If "color" is listed in "excludedFilterKeys", then the query returns the facet values "Red" with count 100 and "Blue" with count 200, because the "color" key is now excluded from the filter. Because this field doesn't affect search results, the search results are still correctly filtered to return only "Red" documents.

A maximum of 100 values are allowed. Otherwise, an INVALID_ARGUMENT error is returned.

Returns:
