Strange behaviour with copyField

I've been hitting my head against a wall all morning trying to figure 
this out and haven't managed to get anywhere and wondered if anybody 
here can help.

I have defined a field type

    <fieldType name="text_au" class="solr.TextField" 
positionIncrementGap="100">
      <analyzer>
        <tokenizer class="solr.LowerCaseTokenizerFactory" />
      </analyzer>
    </fieldType>

I have two fields

<field name="au" type="text_au" indexed="true" stored="true" 
required="false" multiValued="true"/>
<field name="author" type="text_au" indexed="true" stored="false" 
multiValued="true"/>

and a copyField line

<copyField source="au" dest="author" />

The idea is to allow searching for authors so a search for 
"author:(Hobbs A.U.)" will match the au field value "Hobbs A. U." 
(notice the space).

However the query "au:(Hobbs A.U.)" matches and the the query 
"author:(Hobbs A.U.)" does not.

Any ideas?

I'm using a Solr 1.4 snapshot

Regards

James

James,

I don't see the error, but this is exactly what Solr Admin's analysis page will quickly help you with! :)

What is the defaultOperator set in your solrconfig.xml? Are you sure that it
matches for au and not author?

I don't see the difference, as they are the same FieldType for each  
field, text_au.  Is this a typo or am I missing something?

What would lower casing do for handling the space?
