/**
* Pluggable term index / block terms dictionary implementations.
*
* <p>Extension of {@link org.apache.lucene.codecs.uniformsplit} with Shared Terms principle: Terms
* are shared between all fields. It is particularly adapted to index a massive number of fields
* because all the terms are stored in a single FST dictionary.
*
* <ul>
* <li>Designed to be extensible
* <li>Highly reduced on-heap memory usage when dealing with a massive number of fields.
* </ul>
