Assuming: <span id="srchtxt"></span>

// takes one param, expects boolean value
function displaySearchingText( searching ) {

var theSpan = document.getElementById( "srchtxt" );

while ( theSpan.childNodes.length != 0 )
  theSpan.removeChild( theSpan.childNodes.item( 0 ) );

if ( searching )
  theSpan.appendChild( document.createTextNode( "Searching ..." ) );

}
