Subject: Allow facet size to be specified.
X-Git-Tag: ZEBRA.2.0.20~32
X-Git-Url: http://lists.indexdata.dk/?a=commitdiff_plain;h=8d18c2ba52018f0a4149abb5e2bd2bb2c75fe14e;p=idzebra-moved-to-github.git

Allow facet size to be specified.

A facet size may be specified by appending colon and number
after index type, e.g. zebra::facet::title:w:10 .
