Delay search function when using server-side processing

Hello Allan,

i'm wondering if there's already an option for this or if this was already discussed but i've found nothing yet, so:

i'm using datatables with a large mysql database behind (and i really love it by the way :),
but what really bothers me is the behaviour of the search/filter-option in this case.
Every time the user enters a single letter into the searchbox, it is instantly queried to the database, so if i enter a word consisting of 6 letters, 6 sql-queries are made and it takes quiet long to get the result.

Is there any way to delay this process, so that maybe a second or so has to go by till the script is started?

Thanks for your help and greetings from germany,
Bernd
