<p>
    Для раздела <b>Авторы</b>, работу поискового движка можно описать простой фразой: найти авторов по указанным критериям.
    По тем же критериям среди найденных авторов фильтруются книги, сортируются и группируются по сериям.
    <br><br>
    По умолчанию поисковое значение трактуется как "начинается с". Например значение автора "Пушкин"
    трактуется как: найти авторов, имя которых начинается с "Пушкин". Поиск всегда ведется без
    учета регистра - значения "Ельцин" и "ельцин" равнозначны.
    <br><br>
    В поисковых полях "Автор", "Серия", "Название" также доступны следующие префиксы:
    <ul>
        <li>
            "=" поиск по точному совпадению. Например, если задать "=Пушкин Александр Сергеевич" в поле автора,
            то будет найден в точности этот автор
        </li>
        <br>
        <li>
            "*" поиск подстроки в строке. Например, для "*Александр" в поле автора, будут найдены
            все авторы, имя которых содержит "Александр"
        </li>
        <br>
        <li>
            "#" поиск подстроки в строке, но только для тех значений, которые не начинаются ни с одной буквы русского или латинского алфавита.
            Например, значение "#поворот" в поле автора означает: найти всех авторов, имя которых начинается не с русской или латинской буквы и содержит слово "поворот".
            Указание простого "#" в поиске по названию означает: найти всех авторов, названия книг которых начинаются не с русской или латинской буквы
        </li>
        <br>
        <li>
            "?" поиск пустых значений или тех, что начинаются с этого символа. Например, "?" в поле серии означает: найти всех авторов, у которых есть книги без серий
            или название серии начинается с "?".
            Значение "?" в поле названия означает: найти всех авторов, книги которых без названия или начинаются с "?"
        </li>
    </ul>
    <br>
    Специльное имя автора "?" служит для поиска и группировки книг без автора.
    <br><br>
    Для разделов <b>Серии</b>, <b>Книги</b> все по аналогии с авторами.
