LPS-43540 Solr 4 web plugin generating multiple values encountered for non multiValued field for Liferay 6.2

In solr-web4, we add groupId and scopeGroupId fields for solr to index. However, groupId and scopeGroupId includes multiValued, for example, groupId=[10184, 10459, 10465, 10469, 10502, 10506] and scopeGroupId=[10184, 10459, 10465, 10469, 10502, 10506], so add multiValued="true" property in two fields.

Thanks,
