| </head> |
| <body> |
| |
| <h1>The Expressions Module for Apache Lucene</h1> |
| |
| <p> |
| The expressions module is new to Lucene 4.6. It provides an API for dynamically computing per-document values based on string expressions. |
| </p> |
| <p> |
| The module is organized in two sections: |
| <ol> |
| <li>{@link org.apache.lucene.expressions} - The abstractions and simple utilities for common operations like sorting on an expression</li> |
| <li>{@link org.apache.lucene.expressions.js} - A compiler for a subset of JavaScript expressions</li> |
| </ol> |
| </p> |
| <p> |
| For sample code showing how to use the API, see {@link org.apache.lucene.expressions.Expression}. |
