\Zend_Search_Lucene_Field
Package: Zend_Search_Lucene\Document
A field is a section of a Document. Each field has two parts,
a name and a value. Values may be free text or they may be atomic
keywords, which are not further processed. Such keywords may
be used to represent dates, urls, etc. Fields are optionally
stored in the index, so that they may be returned with hits
on the document.
