<section name="About this Document">
<p>
Lucene has a number of properties that can be tuned. They can be adjusted either
programmatically, using the Lucene API, or their default values can be set via
system properties (only up to including Lucene 1.4) described in this document. Starting
with Lucene 1.9, the system properties are not supported anymore and the API
(i.e. the get/set methods) should be used directly.
