Apache SOLR Search in SAP hybris

Search and Navigation module is one of the most requested and intensively used in hybris. It is based on Apache SOLR, which is unarguably the best of breed among all open source search engines available on the market. Understanding the SOLR engine is the must for any developer. Both hybris and Apache parts are well d0cumented, so at the first glance, it should help to progress faster. Actually, this topic will take years to master. I did a lot of research and conducted experiments in the area to get better in SAP Hybris Search.
  • The Challenges of Chinese and Japanese Searching. When it comes to entering “the East”, companies often face many challenges they could not have experienced before. Everything is different in China and Japan including the way how websites are built and how the users interact with them. In this article, I cover one aspect of these challenges: how to adapt product/content search to work with Japanese and Chinese languages.
  • Facet Search: The Most Comprehensive Guide. Best Practices, Design Patterns, Hidden Caveats, And Workarounds.  In this article, I structured the main concepts, best-practices, design recommendations, interaction patterns and visual design considerations for the faceted search. I believe this work covers every aspect of the facet search UI: everything you need to know to create facet search component from scratch or using the ready building blocks from the SAP Commerce Cloud out-of-the-box search module. At the end of the article you will find a summary explaining what features are implemented in the default SAP Commerce Cloud Accelerators; for those which are not implemented, you will find my ballpark estimations of the efforts needed.
  • Autocomplete, Live Search Suggestions, and Autocorrection: Best Practice Design Patterns. In the various sources, the terms like Autocomplete and Suggestions are not defined clearly. They turned out to be too wide to avoid confusion when defining design patterns and software requirements. The customers use the wrong terms in the RFPs, the partners try to use the RFP language and mix that with their own terminology. In this article, I review these topics in depth as well as share my recommendations for the design and implementation.
  • Implementing Product Whitelisting/Blacklisting in SAP Commerce Cloud for Large Product and Customer Bases. Document-level access control ensures that the search results have only those products that a logged customer is authorized to see. This is a common request for B2B solutions with a large and sophisticated product and customer models. Many manufacturers and suppliers want to provide exclusive or restrictive access to products for particular partners. Such an approach reduces the number of incorrect or incomplete orders and makes navigation easier. In this article, we are discussing in detail how to support product whitelisting/blacklisting per customer in SAP Commerce Cloud for large product sets and large customer base. We also present our solution and possible alternatives. The tests showed that the solution is capable to process millions of documents, tens thousands of customers and millions of access rules saying what product is blacklisted/whitelisted for what customer.
  • Multi-line search. (video) The third part is about handling multi-word synonyms in hybris. Hybris doesn’t support phrasal synonyms because of limitations of SOLR, the search engine. I present a module that makes it work via customization of hybris search module. In the fourth part, I tell about automatic facet discovery. This mechanism allows you to deliver better user search experience to the customer by setting up the facets automatically.
  • Search Analytics (video).  This is a second part of the 3-hour presentation given by Rauf Aliev (EPAM SAP hybris Solution Architect) in SAP Moscow on Sep 29, 2017.  In this video, I explain the details of the project of e-commerce search optimization project as well as the details of the software components developed for this purpose.  Using the approach from the video, you will be able to detect the issues with the search configuration, identify the weak points and bottlenecks of your search system, calculate search KPIs for your system and compare the search KPIs before and after the change.
