/* Constructed Search Postprocessing.
 *
 * In order to make everything as seamless as possible, we do a 
 * JS based postprocess on the boolean_search pages.
 *
 * This needs to do two things:
 *   - adjust all the input.name elements.
 *   - push the autoIncrement vars so we don't have modification conflicts.
