Php – How to search zipcodes using Zend Lucene

lucenePHPsymfony1zend-frameworkzend-search-lucene

I have very simple company index with Zend Lucene using this to create the index:

// store company primary key to identify it in the search results
$doc->addField(Zend_Search_Lucene_Field::Keyword('pk', $this->getId()));

// index company fields
$doc->addField(Zend_Search_Lucene_Field::Unstored('zipcode', $this->getZipcode(), 'utf-8'));
$doc->addField(Zend_Search_Lucene_Field::Unstored('name', $this->getName(), 'utf-8'));

I can search on the company name but not the zipcode. Is there a problem with Zend Lucene Search indexing integers? If s/o could shed some light who was experience, please help me out. I can only imagine using Lucene to search by zipcode is pretty common.

I believe the default text Analyzer for Zend Lucene does not search numbers by default. Zend comes packaged with several different text analyzers. Use the TextNum analyzer to search both numbers and characters. There are also a handful of other analyzers in the zend/search/lucene/analysis/analyzer/common folder that you may find useful.

You can change your default analyzer with the following code:

Zend_Search_Lucene_Analysis_Analyzer::setDefault(
    new Zend_Search_Lucene_Analysis_Analyzer_Common_TextNum());

Php – How to exclude searching specified fields using Zend Search (Lucene)

There's currently no way to explicitly not search a field in Lucene's query language, or the Zend_Search_Lucene query constructing API.

However, you can explicitly list which fields you do want to search in a query. An example would be:

seller-name: Joe McBob

If using this approach, you will have to explicitly list which fields you want to query, and what to search in them. So if you also needed to search your item-title field with the same text, you would have to duplicate the above, but with the different field name. An example would be:

seller-name: Joe McBob OR item-title: JoeMcBob

You can, of course, do all this through the query building API that Zend_Search_Lucene provides, as well. The manual has some good examples there.

One thing worth noting here is that, as you've discovered, Zend_Search_Lucene will search ALL fields by default. This is one of the ways in which it differs from Java Lucene. You may, however, set a default field to query, using the setDefaultSearchField static method of the Zend_Search_Lucene class.

Php – Lucene foreign chars problem

I suggest you try using a UTF-8 compatible text analyzer. It looks like the analyzer you are using destroys the non-ASCII characters. You should make sure that the text is input properly, and that it reaches Lucene in the proper format.
