*This method is desinged to recursively iterate through a document, or section of a document, which represents a QVariantMap. As it iterates through the entire document, the method keeps track of the current index expression, and populates a local QVariantMap should the current expression be found in the Index's list of expressions.
*
*If that QVariantMap contains more than one entry it is added to the global results, which can then be utilized by a Query. This needs to be modified to ensure all expressions are found, whereas at the moment if more than one expressions are defined and any of them are found then the map is added to the results list.
