flexible:灵活的
mechanism：机制
通过复写query field names 来提供一个简单灵活的扩展机制的queryparserflexible 后面单开文章翻译讲解
This project contains the new Lucene query parser implementation, which matches the syntax of the core QueryParser but offers a more modular architecture to enable customization.
modular：模块化
architecture：结构
此项目包含新的Lucene query parser 实现，匹配核心queryparser语法但是提供了额外的模块化结构来支持自定义。
It's currently divided in 2 main packages:
{@link org.apache.lucene.queryparser.flexible.core}: it contains the query parser API classes, which should be extended by query parser implementations.
包含query parser api classes，可通过query parser 实现扩展。
{@link org.apache.lucene.queryparser.flexible.standard}: it contains the current Lucene query parser implementation using the new query parser API.surround
