Alexander,
My script section is below:
......
Zend_Search_Lucene_Analysis_Analyzer::setDefault(new
Zend_Search_Lucene_Analysis_Analyzer_Commo
n_TextNum_CaseInsensitive());
Zend_Search_Lucene_Search_QueryParser::setDefaultOperator(Zend_Search_Lucene_Search_QueryParser
::B_AND);
$search = "R\&D"; //I have tried "R\\&D", '"R\&D"',"R&D"
$query =
Zend_Search_Lucene_Search_QueryParser::parse($search);
echo $query->__toString() . "\n";
$hits = $index->find($query);
......
Result output:
"R\&D" --> +(+r +d)
"R\\&D" --> +(+r +d)
'"R\&D"' --> +("r d")
"R&D" --> 'Zend_Search_Lucene_Search_QueryParserException'
with message 'Two chars lexeme expected. Position is 2.'
'"R&D"' --> +("r d")
Besides, I also built the index with
Zend_Search_Lucene_Analysis_Analyzer_Commo
n_TextNum_CaseInsensitive()
Best regards,
David
