doSearch method should url encode values

[alvinlin123]

It's possible we search values with '%' in it. Currently flexgrid will send the '%' character as is to the back-end server, which causes issues during decoding.

Possible solution is to do this in the doSearch() function?
p.query = encodeURIComponent($('input[name=q]', g.sDiv).val());
p.qtype = encodeURIComponent($('select[name=qtype]', g.sDiv).val());
