[VuFind-General] Adding queryfield to "callnumber"

[Christian D. <dab...@fh...>]

Hi all,

I'd like to add a queryfield to the callnumber-query. The value is at 
least in the imported MARC-Data in the field 852 Subfield 9.
I added to marc_local.properties this: callnumber-swf: 8529
Then I added to IndexRecord.php this function to be able to call the 
callnumber where I need it:

     protected function getCallNumberSWF()
     {
          return isset($this->fields['callnumber-swf']) ?
             $this->fields['callnumber-swf'] : '';
     }

In the searchsepcs.yaml I added in the section Callnumber this queryfields:
   - callnumber-swf:
       - [onephrase, ~]

Finally as I wanted to reindex I received the error that the field 
"callnumber-swf" could not be found. What did I do wrong?

thanks in advance,

Christian
