Thanks for all the information, it is being really useful. I didn't know that there were different names for tag clouds, that is also good to know ! I don't feel really comfortable about having search-cloud like information on the index. We would like to have those concerns separated and for this purpose I think the best way would be developing a Request handler or a component to be used inside any Request Handler to store all the query information for search-cloud generation. I have also taken a look at this TermVectorComponent, don't know if it would help me in this issue, anyway it may be useful sometime. Thanks
