Set Search Preferences

The search preferences you configure control the behavior of the search feature for your instance. These preferences can be exported.

Select site > Merchant Tools > Search > Search Preferences.
On the Search Preferences page, select your instance type: Sandbox/Development, Staging, or Production.
In the Availability Settings section:
1. Select Show Orderable Products Only if you want to hide any products that are not available.
  You can also set Show Orderable Products Only at the Product Level.
2. To indicate the percentage of availability from which products are to be ranked lower and pushed to the end of the search results, enter a value in the Availability Low Ranking Threshold field. (For example, 0.3 indicates that all products with an availability of 0.3 and below are pushed to the end of the search result.)
  Ranking is done at query time instead of index building time. Therefore, a change to a rule or threshold takes effect immediately. The results are not sorted by availability; products are shifted via sorting criteria. To control the priority of Availability Ranking and any other sorting criteria in the storefront, use the Sorting Configuration to change the predefined order of possible sorting conditions
In the Search Settings section:
1. Select Dictionary Locale Fallback to make linguistic search rules (stop words, category names exclusions, synonyms, hypernyms, compound words, common phrases, search suggestions, and stemming exceptions) available for a language locale to apply to the related region locales (en_US), in addition to the linguistic rules defined for the region locale itself.
  
  Note:
  Locale fallback in the Search Dictionaries module only works from country locale to language locale, such as en_GB to en. Fallback from language to default locale is not available for Search Dictionaries.
  
  Each page of an affected search rule shows a message that indicates this setting. Disable this setting to have only the linguistic rules defined for the region locale used for this locale.
  
  See Locales.
2. Select Ignore Leading Zeroes to ignore leading zeros for all searchable attributes, such as product IDs.
  For example, when this setting is enabled, searching for 8234 or 008234 finds 008234. Disable this setting and leading zeros are considered part of the search term. For example, only 008234 finds 008234, an exact match.
  
  Note: Rebuild the product catalog to activate this setting.
3. Select Search Autocorrections so that search terms are automatically spell-corrected or completed before the actual search is executed.
  A spell corrected and complete version of the search phrase can appear as Did You Mean regardless of this setting.
  
  Disable this setting and search terms are not corrected or completed.
4. Select Commerce Cloud Einstein Search Recommendations to enable personalized search query correction using Einstein AI.
  See Commerce Cloud Einstein.
5. Select Search Redirect Keyword Rules to use expanded match types: Exact(same as Disabled), Phrase, Broad,, and Negative.
  Disable this setting (default) to use exact match.
  
  See Search Redirects.
6. Select Search Suggestions so that search terms are automatically spell-corrected or completed before the actual search is executed.
  A spell corrected and complete version of the search phrase can appear as Did You Mean regardless of this setting.
  
  Disable this setting and search terms are not corrected or completed.
  
  Enhanced search suggestion is automatically enabled and can't be disabled with this preference. See Search Suggestions.
7. Select Merged Variation Groups Display Mode to enable merging of Variation Groups.
  Variation Groups are shown as individual search hits in the storefront search. In some cases, many individual products can return, so it can be helpful to show all Variation Groups merged as the master product within the search results.
In the Notification Settings for Unbucketed Refinement Values section:
1. Select Notification Email so that the users specified are notified when there are unbucketed refinement values.
2. In the Email To Addresses field, enter one or more comma-separated email addresses for the notification.
  After a new product import, new refinement attributes can be imported that are not accounted for in existing bucketing rules. When products that have non-bucketed values are set to appear, they can cause customer confusion and a poor storefront experience. This setting enables merchants to easily identify these unbucketed values before they appear on the storefront.
  
  If at least one email address is configured, a notification email is sent to that address when unbucketed refinement values are found during indexing.
  
  Don't enable this setting on a Production instance.
In the Notification Settings for Search Indexer section:
1. Select Notification Email so that the users specified are notified when the number of indexing errors exceed the threshold after indexing.
2. In the Email To Addresses field, enter one or more comma-separated email addresses for the notification.
  If at least one email address is configured, a notification email is sent to that address when unbucketed refinement values are found during indexing.
In the Notification Settings for Einstein Dictionaries section:
1. Select Notification Email so that the users specified are notified when there are new search dictionaries available.
2. In the Email To Addresses field, enter one or more comma-separated email addresses for the notification.
Click Apply to save your changes or Reset to revert to the previous settings.
