Increasing the maximum number of results in the searches

[Muflone <webreg vbsimple net>]

Hello

I'm trying to write a simple GS extension which increase the max number 
of results in the searches from the overview.

I've managed to set the number of lines of results using:

injections['createResultContainerActor'] = 
injectToFunction(Search.SearchProvider.prototype, 
'createResultContainerActor', function() {
  global.log('overloaded');
  let grid = new IconGrid.IconGrid({ rowLimit: 3, xAlign: 
St.Align.START });
  let actor = new SearchDisplay.GridSearchResults(this, grid);
  return actor;
});

The previous code overloads the createResultContainerActor for 
SearchProvider creating a new GridSearchResults with 3 lines of results 
items.

During the first search I obtain my three rows of results but after that 
every next searches return only one row of results. This applies to all 
my search providers, as well as the applications provider.

Is there something other I need to monitor to continue to show my 3 rows 
of results during the searches?

TIA
