没有被解析的字段值，被保存，作为单一的Term。
所以使用TermQuery，以值构造new Term。

The purpose of [ Store.YES, Index.NO ] is to allow one to associate information with a document without the waste of indexing that additional information in situations where that information will never be used as serach criteria.
For example, in one of my applications I index the content of a properiatary library. The records in that library are always accessed by a positional index value. As these positional index values are of no use to the end-user of the application, but are needed internally to retrieve the original library document, I associate the positional index with the Lucene document as [ Store.YES, Index.NO ].

The question is that I used:
Field f = new Field("notindex","value",Store.YES,Index.NO);
and then use luke to view those index,and no field value can is there,but the field's value is stored just not index_analyzed when construct the field.
Hope i am clear my question.
thanks

Did that answer your question? :-)
In case it didn't, *analysis* breaks down your field into multiple
tokens. If you don't analyse, (i.e. Index.NOT_ANALYZED) you index your
field as a single token. With Index.NO you don't even index, you just
store the field so its value can be returned in search results.
But maybe that has all been said already :-)
