Response Rewriting

Response rewriting is a strategy for improving relevancy using AI-generated data by modifying Solr’s response before passing it to the search application. There are two approaches to configuring response rewriting:

Rules

Any rule type can add content to the response by modifying the responseValues field. These two rule types can replace the whole response:

• Banner
  Display a user-defined banner message when the rule fires.
• Redirect
  Send users to a different URL instead of the search results.

See the main Rules topic for details.

Query pipeline stages

Query pipeline stages that perform response rewriting must appear after the Solr Query stage. These stages fall into two categories:

• Stages that act on the whole set of results

  • Response Shuffle stage
    ”De-bias” results by shuffling the top N results randomly.

  • Response Pairwise Swap stage
    ”De-bias” results by swapping the search results at any two positions, such as positions 1 and 2, positions 3 and 4, and so on.

• Stages that act on individual documents

  • Response Document Exclusion stage
    Drop all documents that match all of the specified rules.

  • Response Document Field Redaction stage
    Remove fields that match a regular expression from a document.

  • Modify Response with Rules stage

    Apply rules to the response.
