To use the Compound Search feature, select Compound Search from the main reader screen's Lookup menu. In the Compound Search screen, you are presented with the last six kanji characters you have looked up. (If you have not looked up any kanji characters yet, the list will be blank and you will need to look up some characters before you will be able to use the Compound Search.) To search for compounds containing the kanji characters you specify, select the desired characters from the list. If necessary, look up the characters you want using any of the available kanji lookup methods. Then, select whether to search for compounds containing All the selected characters or Any of the selected characters. Finally, tap the Find button to conduct the search.
To replay a dictionary search, simply tap the search entry. To revisit a kanji character's details, tap that character.
