Due to the arrangement of its entries by subject areas, the dictionary of Manchu in five languages (Five-Language Mirror) created by imperial order does not lend itself to direct use as a reference work for unknown word forms. Any alphabetically structured arrangement of the dictionary would only have been able to consider one of the five languages. To make the entries of all languages searchable, indices were created for Manchu, Tibetan (in Romanization of the Tibetan script, but not for the Manchu transliteration systems), Mongolian, Turkic (also here for the Romanization of the Arabic script, but not for the pronunciation indications in Manchu script), and Chinese (organized graphically), which for the first time, in contrast to earlier works, allow for the individual lookup of all word components, including complex compounds.
