Payara 6: Basic search no longer works due to extra, blank url query param

[kcondon]

Basic search seems not to differentiate/work, adv, navbar search do. "Check limited perms" returns all. Seems to refresh the page only, since terms are cleared from search box. They work and remain on demo with correct results shown.

From discussion in tech, there is a double q= param on the url, the first is blank and that is being picked up as the only argument.
