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.
- 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.
