A product search engine is a key element in the functioning of any e-commerce application. It indexes products in real time and produces fast results to queries entered. Currently the solution running on the organization’s website uses a microservice that passes the queries entered, to a third-party service provider that does the indexing and searching. This is a paid service and hence is to be replaced by the open source search engine, Apache Solr. In this paper, we explain the microservice built, using the go-solr package along with the go-kit microservice framework in developing the microservice to replace the pre- existing paid service.
