// Specify the time between keypresses required before the database is searched for suggestions.
// I recommend a value between 350 and 600.  A higher value results in fewer database queries and so a decreased server resource usage.
// Stores with many products (or stores on a shared webhosting plan) are advised NOT specify a value smaller than 500!

var delay = 500;
