It's not in my records yet: the game's still open.

I've seen that mentioned, but I don't understand what it means (that terminology thing again) or how to do a vicinity search.

Well, basically, you take a promising existing puzzle, called the seed, and vary the value(s) of n of its clues (where n is typically 1 to 5), and check whether the result is valid and interesting. When you add filters, for instance to ensure that ED has some minimum value (for instance, not a single), it does become more complicated.

Can gsf sudoku do this (with the correct parameters)? If not, is there another freely available tool to do it?

Sorry, I've no idea. Apart from SE, I've written every line of code I use myself.

I don't know about gsf's programs but ...

If you want to play actively in the game and to find your own strategy, I have no problem to share all my execs (windows) and command lines.
Having all the exec keeps many things open

Just to be clear, compared to Mike and Patrice, I am missing all tools collecting data on the web. On my side, this is purely a manual follow up

For the sake of completeness, there is a further type of vicinity search, namely a stochastic 'walk' through puzzle space. Choose, say, two values to alter simultaneously. If the result fulfils the criteria you're using, change a further two, and so on. You need to check, of course, that you don't get back to where you started and loop forever.
