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?

Answer 1

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.
