Hi,
I have a query term like this:
$query="apple NOT banana AND fruits";
$query="a1 NOT prim1 AND a2 NOT a3 OR a5";
I want to apply brackets to the NOT terms and the output should be like this:
$query="apple NOT (banana) AND fruits";
$query="a1 NOT (prim1) AND a2 NOT (a3) OR a5";
How can i do this??
Regards
Vanitha
