Refer the below queries for example
/jcr:root/content//*[@pageTitle='GeoMetrixx' or @jcr:title='Geometrixx Media']
In the above query i am searching with two properties pagetitle and jcr:title with OR operator.Even AND operator work as well.
/jcr:root/content//*[@cq:template='/libs/cq/core/content/projects/templates/creative-project-management' or @cq:template='/libs/cq/core/content/projects/templates/default'] which searches for cq:template property with 2 different values.
