Why can't I find the "0" field in Solr?

Question

From schema.xml:

<field name="myfield" type="integer" indexed="true" stored="false"/>

The record with identifier 5 has myfielda value of 0, which I confirmed by doing a plain search id:5and looking at objectXml.

Search id:5 AND myfield:0does not return records.

The search id:5 AND -myfield:1, however, returns the expected record.

Why?

- Additional Information:

Definition for integer type: <fieldType name="integer" class="solr.IntField" omitNorms="true"/>

Solr Version: 1.4

Answer 1

I solved the problem. It was a bug in the application core (third-party CMS) and had nothing to do with Solr.
