Subject: New function delimitQuery().
X-Git-Tag: 0.9.1~148^2~57
X-Git-Url: http://git.indexdata.com/?a=commitdiff_plain;ds=sidebyside;h=5c7b651bae92f6863a79666ef94678b940f9cf72;p=mkws-moved-to-github.git

New function delimitQuery().
New function redraw_navi() handles drawing all selected facets,
	whether based on field values or source.
This is now used by limitQuery(), limitTarget(), delimitQuery() and
	delimitTarget().
(These methods have too much shared code at the moment -- I'll fix
	that shortly, but want to check in the first working version.)
