Return row data from a table with a specified row without looping through all rows

Question

I have a task: I need to return all Row data containing a user-defined string .

One way to achieve this goal is to iterate over all the rows , but this only works when you know which column to search in , as shown, using the code below.

var sheetData = SpreadsheetApp.getActiveSpreadsheet().getDataRange().getValues();
var searchString = "testSearch";

for(var i=0;i<sheetData.getLastRow();i++)
{
  //assuming we know that the search string is going to be in Column 2
  if(sheetData[i][1].search(searchString)!=-1)
  {
    var rowData = sheetData[i];
    return rowData;
  }
}

So, my question: Is there any way that we can achieve , without having all the strings cycle through one ?
