This stage uses the content of the current document to query for similar documents, using Solr’s MoreLikeThis component. This stage provides content-based recommendations. For collaborative recommendations, use the Recommend Items for Item stage. See Recommendations and Boosting for more information.

​
Tips

  • The incoming query must include an id field in order to get recommendations from this stage. The stage returns documents similar to the one specified by this field.
  • Since these secondary queries tend to be large, this stage can impact search performance. You can improve performance by first clustering your documents, then configuring this stage to query a specific document cluster instead of all documents.

Configuration
