Как настроить Search View из библиотеки appcompat-v7-25.3.1-sources.jar

Некорректно выполняется поиск элементов из списка, при вводе какого либо значения. Есть элемент, но в поиске его не находит.

Есть допустим более 100 элементов в списке. Ввожу напрямую первое слово, но в списке его нет, ровным счетом как и других элементов. В чем загвоздка?
