What are the various ways of optimizing Lucene performance?
Shall I use caching API to store my lucene search query so that I save on the overhead of building the query again?

Why is Lucene faster? Lucene is very fast at searching for data because of its inverted index technique. Normally, datasources structure the data as an object or record, which in turn have fields and values.
Last I checked, Lucene doesn't use B-trees. It uses a variation on skip lists to implement efficient inverted indices.
Lucene uses a well-known index structure called an inverted index. Quite simply, and probably unsurprisingly, an inverted index is an inside-out arrangement of documents in which terms take center stage. Each term refers to the documents that contain it.
