More than searching, rendering eats up a lot of time and resources. Limit the number of rows to display and your code can work like a charm. Also instead of hiding and unhiding, if you print only limited rows, that would be better. You can check out how it's done in my opensource library https://github.com/thehitechpanky/js-bootstrap-tables

    function _addTableDataRows(paramObjectTDR) {
    let { filterNode, limitNode, bodyNode, countNode, paramObject } = paramObjectTDR;
    let { dataRows, functionArray } = paramObject;
    _clearNode(bodyNode);
    if (typeof dataRows === `string`) {
        bodyNode.insertAdjacentHTML(`beforeend`, dataRows);
    } else {
        let filterTerm;
        if (filterNode) {
            filterTerm = filterNode.value.toLowerCase();
        }
        let serialNumber = 0;
        let limitNumber = 0;
        let rowNode;
        dataRows.forEach(currentRow => {
            if (!filterNode || _filterData(filterTerm, currentRow)) {
                serialNumber++;
                if (!limitNode || limitNode.value === `all` || limitNode.value >= serialNumber) {
                    limitNumber++;
                    rowNode = _getNode(`tr`);
                    bodyNode.appendChild(rowNode);
                    _addData(rowNode, serialNumber, currentRow, `td`);
                }
            }
        });
        _clearNode(countNode);
        countNode.insertAdjacentText(`beforeend`, `Showing 1 to ${limitNumber} of ${serialNumber} entries`);
    }
    if (functionArray) {
        functionArray.forEach(currentObject => {
            let { className, eventName, functionName } = currentObject;
            _attachFunctionToClassNodes(className, eventName, functionName);
        });
    }
}
