Issue2550934 - templating.py-indexargs_form() returns id's as space separated list not comma separated Compare filter=id&id=1+2+3+4+5+6+7 (+ means space) to filter=id&id=1,2,3,4,5,6,7 the latter seems to be a valid filter and the index page search will return items with those 7 id's. The former does not return the expected 7 items. Check to see if the name of the field is id. If it is don't treat it as a string which pastes all the values together with spaces.
