The sorting of Tibetan terms conforms to how they are spelled out in Tibetan, rather than the traditional arrangement based on the root letter. Therefore a term like མདོ། (spelled: མ་ + ད་ + ོ) will be found under མ་. The same applies to superscribed letters, like རྡོ། which will be listed as if spelled ར་ + ད་ + ོ.
