My team is building next generation eCommerce search platform for major an online retailer with quite challenging business requirements. Turns out, default Lucene toolbox doesn’t ideally fit for those challenges. Thus, the team had to hack deep into Lucene core to achieve our goals. We accumulated quite a deep understanding of Lucene search internals and want to share our experience. We will start with an API overview, and then look at essential search algorithms and their implementations in Lucene. Finally, we will review a few cases of query customization, pitfalls and common performance problems.
