The Expressions Module for Apache Lucene

The expressions module is new to Lucene 4.6. It provides an API for dynamically computing per-document values based on string expressions.

The module is organized in two sections:

1. The Expressions Module for Apache Lucene - The abstractions and simple utilities for common operations like sorting on an expression

2. Lucene.Net.Expressions.JS - A compiler for a subset of JavaScript expressions

   For sample code showing how to use the API, see Expression.
