Thanks, Sergiu, First of all: the body of all comments liked to given group of users. Then, I would like to understand how comments could be retrieve to have full control about what I'm getting. I do need all three queries you list, then I also like to be able to answer questions as: 1. Tabulated how many replies users posted in all pages of a given space like the one below on a per user/per page basis? http://atriumkm.idisantiago.es/bin/OpenInitiative/InVitroPreclinicalModels2… 2. What is the name and the surname of the users holding a comment with a given string in one of her/his comments? I found comments, spaces and groups really interesting "metaphors" available out of the box with XWiki to store different kinds of information without effort. But that effort must be done while retrieving it!!! All of these pieces of information could be stored in a more "structured" way designing ad hoc classes, creating "applications in a minute", and so on, so forth... but, for instance, comments, are really useful to make our mind about what we want to "translate" to an application. I do hope this has sense for you!

In this case, since the snippet is showing the last comment, the query needs to return at most one row. Maybe you changed the query in the mean time, but I can see both comments displayed when you don't set the limit. Hope this helps, Marius

There's nothing wrong with that. setLimit() sets the maximum size of the returned list. In the first case the list has maximum one element, and in the second case it has the size equal with the number of matching rows found in the database. Hope this helps, Marius
