X-Git-Tag: YAZ.2.0.8~11
X-Git-Url: http://git.indexdata.com/?p=yaz-moved-to-github.git;a=commitdiff_plain;h=b7dce0eae6656ccb499233e04f5a5bf90178c7cd

All changes to the CQL section:
Talk about context sets instead of index sets.
Talk about indexes instead of qualifiers.
Document new "index.set.name" specifier.
(The old "qualifier.set.name" specifier is mentioned as DEPRECATED.)
Describe default use of cql.serverChoice instead of srw.serverChoice.
Update the example configuration file according to the above.
