Most query parsers don't support wildcards in phrases. Do you really need
phrase matches in your article numbers?
If so you might need to experiment with the ComplexPhraseQueryParser
<https://solr.apache.org/guide/solr/latest/query-guide/other-parsers.html#complex-phrase-query-parser>.
Your examples look like they don't need
that complexity and could even work without the wordDelimiterGraph filter
or even with a simple String field.
