Description

Just encounter such weird behaviour, will recheck and followup.
{

{"filter":["\{!v=$bogus}

"]}} responds back with just NPE which makes impossible to guess the reason.
It might be even worse, since {

{"filter":[\{"param":"bogus"}

]}} seems like just silently ignored. Turns out it's ok see SOLR-9682
