Using Fast-Indexed Content

Once data has been fast-indexed, it is possible to use the name of that content element as an XPath variable for any of the operations on metadata. For example, if you fast-index a content with name "price", you can write the XPath expression $price > 10.15 to filter results or you can do binning on the $price. See the next section for more information on using XPath expressions and operators in your queries.
