As we countdown to the annual Lucene/Solr Revolution conference in Boston this October, we’re highlighting talks and sessions from past conferences. Today, we’re highlighting Peter Gazaryan and Eugene Steinberg’s talk, “Deep Data at Macys: Searching Hierarchical Documents for eCommerce Merchandising”.

The traditional notion of relevance focuses on the “information need”. In eCommerce, online customer’s “information need” is the desire to locate and obtain information about products. A naïve approach to product catalog search focuses entirely on the customer’s query, and ranks the results using standard methods, such as TF/IDF. While this methodology may be good for general purpose eCommerce venues like online bazaars, it ignores the key tenet of the Department Store business model: Merchandising.

Macy’s has expanded Solr with advanced Merchandising capabilities: fine-grained control of precision over recall, dynamic grouping and ungrouping of related entities, cross-entity match elimination, rule-driven search query rewriting, and combinatorial concept search. This talk describes the history of Macy’s implementation and highlights lessons learned.
