Solr 4.0, TextField query gives NullPointerException

Question

I have a field in my Solr schema like -

Type - <fieldType name="text" class="solr.TextField" positionIncrementGap="100"/>
Declaration - <field name="description" type="text" indexed="true" stored="true"/>

This description field has values for some documents and no data for the remaining. I am not explicitly setting anything when there is no data for the description field as it is not a required field.

The problem is when i query using - description:*. I get a NullPointerException.

I have not changed the schema. Also when I query description:abc it works however for description:* and description:abc* it gives a NullPointerException.

Is it the correct behavior?
Are the text fields required to be given "" values when we do not have to set it?

A field of type solr.TextField has to have a Tokenizer associated with it otherwise it fails for wild character search.

I created a Jira bug for the same here.

It should work and does normally work.

Did you by any chance change field type definition and then did not do a full-reindex (delete old index and so on)?

I have seen this before but it seemed to have gone away after the index was fully rebuilt. May be something to do with left-over definitions on Lucene level.

Nope. I started afresh and still the same problem. Infact when I add the same field in facet it gives me a facet. But on searching it fails. Also if search for `description:the` it works but the moment i add a `*` in the end it fails. – JHS Jan 18 '13 at 17:23

If you can easily reproduce it, you probably want to create a JIRA issue for Solr. In a meanwhile, do you by any chance have a dynamic field for * or maybe description*. Try to see if there is a minimal problem case. – Alexandre Rafalovitch Jan 18 '13 at 17:52
