QueryElevationComponent can detect changes to its elevate.xml file and load it following a commit (new searcher). But this only works when the file is in the "data" dir, which is weird. I wish to support for the data dir and add this auto-loading mechanism to standard conf/configSet location. Additionally, I wish to QEC's support of the elevate.xml file to be "versioned" – e.g. elevate.xml.001, elevate.xml.002.
