今天，犯了个低级错误…做查询的时候发现lucene用queryparser只有完全等值才能匹配。</p>
经过排查原来是在建立索引的时候使用了StringField作为字段（这个只支持全值相等）
改为TextField方可模糊查询……
baidu好多资料是没有发现的……
后来看到官方某个角落的文档发现了这个，才想起来怎么回事……感冒中……

A field is a section of a Document. Each field has three parts:name, type and value. Values may be text (String, Reader orpre-analyzed TokenStream), binary (byte[]), or numeric (a Number).Fields are optionally stored in the index, so that they may bereturned with hits on the document.
NOTE: the field type is an <code STYLE="font-family:" DEJAVU="" SANS="" PADDING-TOP:="" MARGIN-TOP:="" LINE-HEIGHT:="">IndexableFieldType</code>. Making changes to the state ofthe IndexableFieldType will impact any Field it is used in. It isstrongly recommended that no changes be made after Fieldinstantiation.
