Luigi's Box vs Elastic Enterprise Search: Which is best for you?

luigi’s box plugged into our shop in a single afternoon, and its self-learning autocomplete, semantic ranking, and cross-sell widgets immediately surfaced the most relevant products, guiding shoppers from query to checkout with almost no manual tuning.

We tried to increase the conversion rate from search, because we only used simple search, which did not help customers find what they were looking for.

I have worked with Apache Lucene and Elasticsearch just saves all that trouble of dealing with the indices all the time in Lucene and rather provides seamless integration through APIs for search queries.
