A complete new install of lubuntu 11.10 has synaptic 0.75.2ubuntu7. Previously when using synaptic on another system there was a search box in the tool bar where a search string could be entered which would reduce the displayed packages as the string was being entered. The box is not being displayed nor do I find any setting to enable/disable it.

Unfortunately this solution does not work for me (ubuntu x64 12.10 fresh install) – JoZ3 Apr 10 '13 at 17:12

If the other answers don't help then try:

sudo apt-get install --reinstall synaptic
sudo dpkg-reconfigure synaptic

It worked for me.

forums linuxmint suggests installing apt-xapian-index when the box is present but grayed out. This solution also works in this case where the Quick Filter box is completely missing.
