Go to HKEY_CURRENT_USER\Software\Kazaa\Advanced\ Open the MaxSearchResult key.
Change it to Hex: 4e20 or decimal: 20000. Now Kazaa (any version) will allow up to 20000 results for each individual search.
Opening the Kazaa options dialog and going to the advanced tab is aggrivating after changing this. Since all the settings in the Kazaa options dialog is in the registry, seems you guys could replace the entire dialog with a K++ version which incorporates your options also. Why not? Hell, make me part of the development team and I'll do it.
