Hi Nathan in QGIS we have something similar, maybe not that advanced: look for QgsSearchString and QgsSearchTreeNode classes. They were originally created for advanced search in the attribute table supporting a subset of SQL, more recently it is possible to use those classes also for evaluation of expressions.
