В качестве данных в следующих тестах будут использованы поисковые фразы (SearchPhrase), URL и PageCharset.
Строка SearchPhrase непустая только в 6.8% случаев. Средняя длина непустой строки - 47 байт.
URL почти всегда непуст и его средняя длина - 77 байт.
PageCharset тоже почти всегда непуст, но его средняя длина поменьше - 6.2 байта. -->
