The LuceneSail comes in three flavors. This page provides an overview of their features, pros and cons, so that you can select the one that serves your needs.

Original Hits-set Triple-Store?
Description The original Lucenesail as maintained in the trunk of the svn. With Sesame 2.1, Graph Queries do not work anymore, so if you rely on such queries, consider using one of the other flavors. The Hits-set flavor has a much better performance for queries that contain multiple LuceneSail queries. The Triple-Store flavor is a complete rewrite of the internal evaluation of the LuceneSail. Here, the LuceneSail optimizes and evaluates the query itself. This is done similar to the Native and Memory Store. It also provides more new features than the other flavors.
GraphQueries? only the 2.0 branch YES YES
multiple queries for the same resource NO NO YES
per-query limit of results NO NO YES
