Query rewrite rule types

• Head/Tail. Replace underperforming queries with queries that produce higher click-through rates. Query improvements always require review before they are published. Schedule the Head/Tail Analysis job to get AI-generated query improvements based on your signals collection.
  
  Manually created Head/Tail rewrites must provide an “Improved Query” in a format appropriate to the type of request the rewrite will be applied to. For Legacy requests, this means a valid Solr query fit for use as the q parameter. For DSL requests this means a JSON string representing the main DSL query.

  • Underperforming Query Rewriting
  • Head/Tail Analysis Jobs
• Misspelling. Managed Fusion replaces misspelled query terms with their spelling corrections for better search results. Schedule the Token and Phrase Spell Correction job to get AI-generated spelling corrections based on your signals collection. See Misspelling Detection.
• Phrase. Known phrases are boosted when they appear in new queries. Schedule the Phrase Extraction job to get AI-generated phrases based on your signals collection. For more information, see Phrase Detection.
• Synonym. Synonyms are used to expand queries so that they include all known synonyms of the query terms. To retrieve AI-generated synonyms based on your signals collection, schedule the Synonym Detection job.
• Remove Words - Remove particular phrases from queries. Unlike other rewrites, these should be entered manually and are not generated by a job. See Remove Words.

Reviewing auto-generated phrases

• Auto These results have a confidence level as a threshold to automatically deploy them to the _query_rewrite collection. This threshold can be specified in the configuration parameter Minimum Likelihood Score (default value 0.1). No action is required on these results, but you can edit them if you wish.
• Pending The confidence level is ambiguous, and the result must be reviewed by a user before it can be deployed. It will only be moved from the _query_rewrite_staging collection to the _query_rewrite collection when its status has changed to “Approved” and it has been published.

​

How to review a pending phrase result

1. Navigate to Relevance > Rules > Rewrite.
2. Select Phrase tab. The application displays the Phrase Detection screen.
   Notice the Status facet on the left. Click Pending to view only the items that need review.
3. Click the icon next to the phrase.
4. In the Status column, select either “Approved” or “Denied”. Optionally, you can also edit the phrase itself.
   Although the Confidence field is also editable, changing its value makes no difference.
