This module provides a number of queryparsers:

这个module提供了这些queryparsers：

• classic：一个简单的用javacc实现的Lucene queryparser

• analyzing
  QueryParser that passes Fuzzy-, Prefix-, Range-, and WildcardQuerys through the given analyzer.
  处理fuzzy- prefix- range- wildcardquerys的queryparser

• complex phrase
  处理复杂的query语法 例如 (john jon jonathan~) peters*

• extendable
  Extendable QueryParser provides a simple and flexible extension mechanism by overloading query field names.
  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queryparser

• flexible 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
  A QueryParser that supports the Span family of queries as well as pre and infix notation.
  notation：符号
  一个 QueryParser 支持span系列查询例如pre和infix符号。

• xml
  A QueryParser that produces Lucene Query objects from XML streams.
  产生Lucene query objects xml 流。
