Zend Lucene - cannot search numbers

Question

Using Zend Lucene I cannot search numbers in description fields

Added it like this:

$doc->addField(Zend_Search_Lucene_Field::Text('description', $current_item['item_short_description'], 'utf-8'));

Googling for this showed that applying following code should solve the problem, but it did not..:

Zend_Search_Lucene_Analysis_Analyzer::setDefault(new Zend_Search_Lucene_Analysis_Analyzer_Common_TextNum_CaseInsensitive());

any thougts?

Answer 1

You have to set the default analyzer twice: On the indexing process as well as on the searching process.

Use the code line from above:

Zend_Search_Lucene_Analysis_Analyzer::setDefault(new Zend_Search_Lucene_Analysis_Analyzer_Common_TextNum_CaseInsensitive());

Answer 2

Did you use that command before or after calling Zend_Search_Lucene::open()?

Calling it beforehand definitely works.

Answer 3

I'm not sure about 'zend', but for deal with number in lucene, you need use following technique:

• To place int to document use following:

  document.Add(new Field(FIELD_SPEC, NumberTools.LongToString(YOUR_INT), Field.Store.YES, Field.Index.UN_TOKENIZED));

• To locate value use Term: Term(FIELD_SPEC, NumberTools.LongToString(YOUR_INT))
