Comment 5 for bug 948820

Both of my suggestions for how to fix this need to be completed in Unity. We could put the string length limitation in hud-service but to do so would be bad because the user interface would still allow longer strings to be entered -- we would simply ignore them. The limitation needs to be in the UI.

The other part of fixing this -- which is not submitting a query while one is still active -- definitely can only be done in the front-end.
