title: jqGrid clear search criteria
body: <p>Currently I have a grid set up with the search enabled. When I run a search everything works fine and I can return good data back to the grid. I see that the "_search" parameter on the URL is set to "true" and all is well.</p>
  
  <p>However, when finished with the search and the data is no longer relevant, I would like to reload the grid to display the previous data that was there (the data displayed on the initial pageload). I made a function to call the "trigger("reloadGrid")" method, but that just sends the same data with the "_search" still set to "true".</p>
  
  <p>Is there a way to clear out the search request data and just reload the initial data shown on pageload or at least set the "_search" value back to "false" so I can check against it? Currently the only way to display the original data is to reload the page.</p>
