dynamic result cluster

[Laurent]

We had to redo the dynamic result cluster because the original works
with AJAX which creates lots of problems for people with disabilities.
We manage to get working without AJAX but it significantly impacts
performance because the data sent by the server is way too great (6
time the size of an average search result XML).

Are there search parameters available to control what information is
sent by the clustering web service?

Thanks in advance for your help.
