Hi Thorsten, How exactly are you executing the queries? If you're using shell commands, keep in mind that the shell will apply its own escaping rules to your command parameters first so if you're not careful a backslash might already be "eaten" before the actual request is fired of. Same goes for any string escaping rules in the programming language you might be implementing your test script in.
With echoParams=explicit you can see what ended up being sent to Solr, but keep in mind that JSON also uses backslash as an escape character. This is one case where wt=xml can actually help avoid confusion.
