To be clear, no clean way to do *expansion* as opposed to reduction at query time, when the alternatives are of different lengths. You could use index-time expansion, a combination of index time and query time reduction on the same synonym dictionary, or only handle the multi-token alternatives during indexing with expansion, and do query-time synonym expansion on the remaining alternatives. -Yonik
