cubicweb #1863109 facet / bookmark search doesn't escape values [validation pending]
When I use facets, if the original rql query contains + characters such as in:
Any X, GROUP_CONCAT(XA + " " + XB) ...
they get unquoted in the bookmarked query and .. disappear:
Any X, GROUP_CONCAT(XA " " XB) ...
and the RQL becomes invalid
