Automatic completion needs improvement

[GoogleCodeExporter]

What steps will reproduce the problem?

If the word "Term" is entered in the input field, there are many options for 
auto-completion, e.g. "academic term. Once more letters of the word 
"Terminator" are entered, e.g. "Termin", you get no options. Entering "Termina" 
produces two options, for "Terminat" we get one and for "Terminat" again zero 
options. Only when the entire word "Terminator" is entered, the requested 
resources are displayed.

Such behavior is confusing and gives the impression that the requested resource 
does not exist.
