Term queries can be used for searching with a single term.
Query string:
word1
or
Query construction by API:
<?php
$term = new Zend_Search_Lucene_Index_Term('word1', 'field1');
$query = new Zend_Search_Lucene_Search_Query_Term($term);
$hits = $index->find($query);
The term field is optional. Zend_Search_Lucene searches through
all indexed fields in each document if the field is not specified:
<?php
// Search for 'word1' in all indexed fields
$term = new Zend_Search_Lucene_Index_Term('word1');
$query = new Zend_Search_Lucene_Search_Query_Term($term);
$hits = $index->find($query);
