Description
An enhancement to CRC to run queries against derived fact tables (Multi-fact tables) as found in OMOP or PCORI.
Enabled by a crc.properties parameter
# Derived fact table parameter
queryprocessor.derivedfacttable=true
If parameter does not exist, then queries run against obs_fact table.
On 1/4/17 added capability to query more than one domain for the case of a concept folder whose children span more than one domain (eg labs with measurement and observation) Each concept is assigned to one domain but a folder may have children within a separate domain.
In the case for no filter list, OMOP returns an empty observation set by default. The reason for this is there since there are no concepts in the filter list, we dont know which domain table to query
