Фильтр контента по буквам на jquery

Таким поиском очень удобно фильтровать большие объемы данных, например таблицы.

Пример:

HTML:

<input class="search-input form-control" type="text" placeholder="Введите несколько букв для фильтрации" />
<table class="filter-table table table-striped">
<thead>
<tr>
<th>№</th>
<th>Страна</th>
<th>Население</th>
<th>Дата</th>
<th>% от населения Земли</th>
</tr>
</thead>
<tbody>
<tr class="filter-row">
<td>1</td>
<td class="filter-title">Китай</td>
<td class="filter-title">1&nbsp;402&nbsp;170&nbsp;000</td>
<td class="filter-title">21 марта 2020</td>
<td class="filter-title">18.03%</td>
</tr>
<tr class="filter-row">
<td>2</td>
<td class="filter-title">Индия</td>
<td class="filter-title">1&nbsp;369&nbsp;604&nbsp;000</td>
<td class="filter-title">21 марта 2020</td>
<td class="filter-title">17.61%</td>
</tr>
<tr class="filter-row">
<td>3</td>
<td class="filter-title">США</td>
<td class="filter-title">331&nbsp;427&nbsp;186</td>
<td class="filter-title">4 июня 2019</td>
<td class="filter-title">4.26%</td>
</tr>
<tr class="filter-row">
<td>4</td>
<td class="filter-title">Индонезия</td>
<td class="filter-title">266&nbsp;911&nbsp;900</td>
<td class="filter-title">1 июля 2019</td>
<td class="filter-title">3.43%</td>
</tr>
<tr class="filter-row">
<td>5</td>
<td class="filter-title">Пакистан</td>
<td class="filter-title">217&nbsp;209&nbsp;656</td>
<td class="filter-title">21 марта 2020</td>
<td class="filter-title">2.79%</td>
</tr>
