      • getExcludedFilterKeysList

        public com.google.protobuf.ProtocolStringList getExcludedFilterKeysList()
         List of keys to exclude when faceting.


 By default,
 [FacetKey.key][google.cloud.retail.v2.SearchRequest.FacetSpec.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 products with the color facet "Red"
 and 200 products with the color facet "Blue". A query containing the
 filter "colorFamilies:ANY("Red")" and having "colorFamilies" as
 [FacetKey.key][google.cloud.retail.v2.SearchRequest.FacetSpec.FacetKey.key]
 would by default return only "Red" products in the search results, and
 also return "Red" with count 100 as the only color facet. Although there
 are also blue products available, "Blue" would not be shown as an
 available facet value.

 If "colorFamilies" is listed in "excludedFilterKeys", then the query
 returns the facet values "Red" with count 100 and "Blue" with count
 200, because the "colorFamilies" 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" products.

 A maximum of 100 values are allowed. Otherwise, an INVALID_ARGUMENT error
 is returned.
        repeated string excluded_filter_keys = 3;
        Specified by:
        getExcludedFilterKeysList in interface SearchRequest.FacetSpecOrBuilder
        Returns:
        A list containing the excludedFilterKeys.

      • getEnableDynamicPosition

        public boolean getEnableDynamicPosition()
         Enables dynamic position for this facet. If set to true, the position of
 this facet among all facets in the response is determined by Google
 Retail Search. It will be ordered together with dynamic facets if dynamic
 facets is enabled. If set to false, the position of this facet in the
 response will be the same as in the request, and it will be 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 will be determined by
 Google Retail Search.

 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 enable, which will generate 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 Google Retail Search orders "gender" and
 "rating" facets. However, notice that "price" and "brands" will always be
 ranked at 1st and 2nd position since their enable_dynamic_position are
 false.
        bool enable_dynamic_position = 4;
        Specified by:
        getEnableDynamicPosition in interface SearchRequest.FacetSpecOrBuilder

 ("price", "brands", "rating", "gender") or ("price", "brands", "gender",
 "rating") depends on how Google Retail Search orders "gender" and
 "rating" facets. However, notice that "price" and "brands" will always be
 ranked at 1st and 2nd position since their enable_dynamic_position are
 false.
        bool enable_dynamic_position = 4;
        Parameters:
        value - The enableDynamicPosition to set.
        Returns:

      • clearEnableDynamicPosition

        public SearchRequest.FacetSpec.Builder clearEnableDynamicPosition()
         Enables dynamic position for this facet. If set to true, the position of
 this facet among all facets in the response is determined by Google
 Retail Search. It will be ordered together with dynamic facets if dynamic
 facets is enabled. If set to false, the position of this facet in the
 response will be the same as in the request, and it will be 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 will be determined by
 Google Retail Search.

 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 enable, which will generate 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 Google Retail Search orders "gender" and
 "rating" facets. However, notice that "price" and "brands" will always be
 ranked at 1st and 2nd position since their enable_dynamic_position are
 false.
        bool enable_dynamic_position = 4;
        Returns:
        This builder for chaining.
