How do I detect "ERROR:SCHEMA-INDEX-MISMATCH" in Solr?

Question

How do I find documents in my index that have a SCHEMA-INDEX-MISMATCH? I have a number of these that I am finding them by trial-and-error. I want to query for them.

The results that I get have "ERROR:SCHEMA-INDEX-MISMATCH" in a field. An example:

<?xml version="1.0" encoding="UTF-8"?>
<response>
    <result name="response" numFound="1" start="0" maxScore="12.993319">
        <doc>
            <float name="score">12.993319</float>
            <str name="articleId">ERROR:SCHEMA-INDEX-MISMATCH,stringValue=555</str>
            <str name="articleType">Knowledge Base</str>
            <str name="description">Moving to another drive Question: How can I ....</str>
            <str name="id">article:555</str>
            <str name="title">Moving to another drive</str>
            <str name="type">article</str>
        </doc>
    </result>
</response>

If it matters, my query is along the lines of http://server/solr/select?q=id:%22article:555%22

Answer 1

What is the "type" of articleId?

I had issues with a date field and due to a defect in indexing program, I had 'ERROR:SCHEMA-INDEX-MISMATCH". Since these are values out side the bounds of a normal date, I was able to find them by the query - "Not myDateFieldType:[0001-01-01T00:00:00Z NOW]" .

If you are able to craft this type of query, depending on your data type, you should be able to find these values.
