Search is not working

Keyword search is not possible when the server option is set to true.

## Expected Behavior
The rows containing the keyword should be visible

## Current Behavior
The rows are not filtered according to the searched keyword.

## Steps to Reproduce (for bugs)
Here's my mui data-table configuration
const options = {
page: page,
rowsPerPage: rowsPerPage,
count: count,
serverSide: true,
filter: true,
filterType: "dropdown",
responsive: 'vertical',
tableBodyHeight: "550px",
onTableChange: (action, tableState) => {
console.log(tableState);
console.log("action ==> ",action);
if(action === "changePage" || action === "changeRowsPerPage"){
this.changePage(tableState.page, tableState.rowsPerPage);
}
}

Start by tracing the serverSide option and the onTableChange callback in the table implementation, using the supplied configuration to reproduce the search behavior. Inspect how search actions and table state are handled; done means keyword search causes the expected matching rows to be visible when serverSide is true, with coverage for this configuration.
