[TYPO3-Solr] Query Filter negate

[Hendrik Nadler]

Hi List,

I`m trying to filter out some (at the moment)  unwanted search results by adding a filter to 

plugin.tx_solr.search.query.filter {
...
}

Certain URLs should _not_ be displayed. How do I add a filter that sorts out URLs e.g. matching "/foo/". I tried so many variants like -url=/foo/ !url=foo etc. and nothings works for me. Any ideas?

Thx a lot and regards, Hendrik
