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 ]. - Neal

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 At 2012-10-01 15:34:44,Upayavira <u...@odoko.co.uk> wrote: >Did that answer your question? :-) > >In case it didn't, *analysis* breaks down your field into multiple >tokens.
