Warning: IE url length maximum is 2083 characters. If urls are longer than maximum you can shorten the url by replacing escape characters (the 3-character groupings that start with percent signs) as follows:
%5B with [
%5D with ]
%28 with (
%29 with )
If still too long remove the space before the left square brack (replace %20[ with [) and check that you are using abbreviated field/index tags. Also check to remove unnecessary repetition of terms.
