bug fixed: Hitting [Enter] after adding a search text is preventing the results from showing.

It is very notable with remote ajax search. You key in your text, the dropdown changes to "Searching..." and then if you hit [Enter] before the server responds, the search text is cleared out and the dropdown keeps showing "Searching..." forever. If you repeat the same search, the results are showing right away because they are cached.

Everything works fine you don't hit the [Enter] key.
