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:
org.apache.lucene.expressions
- The abstractions and simple utilities for common operations like sorting on an expressionorg.apache.lucene.expressions.js
- A compiler for a subset of JavaScript expressions
For sample code showing how to use the API, see Expression
