The problem is that i didn't store the mediacode in a field. Because the code
is used frequently for getting the customer source.
So far i've found the "solr.WordDelimiterFilterFactory" which is (from Wiki)
the way to go. The problem seems to be that i'm searching a "longer" string
then i've indexed. I only index the numeric id (12345).
But query string is BR12345. I don't get any results. Can i fine-tune
the WDFF somehow?
By using the admin/analysis.jsp
