Typing fast misses keystrokes - very wierd....

[robov]

I have a select2 ajax implementation and it works marvelous Now I noticed something very wierd... when i type in (really fast) 'hypertension' The final call to the server is ?q=hypertensio (without the last n) The result is that the selectbox is empty...

When I backspace on the n it searches again "?q=hypertensio" and the proper values are diplayed in the box

When I then type the closing n again it searches and results correctly ( ?q=hypertension)

To make it even wierder... when i type in (really fast) 'hypertension ' (with an extra space) Then the search is again correct ?q=hypertension+

Any ideas ?

This is more a plugin question (you may post to the author). But to answer, the behavior is typical of any ajax based search input box... you normally have a delay after which the ajax search is executed (for performance reasons)... and not instantly... so as a user you are expected to wait after some typing to get the search results.
