Very helpful. Regarding /o, now it makes sense (the cycling nature of the retrieval) and, yes, it seems to be working just fine. Because some of the groups in the virtual collection have not had any recent activity, I was confused by seeing significantly old articles in the list provided. I now know that I need to multiply the number of messages, M, to retrieve by N, where N is the number of groups in the virtual collection, to ensure I get the M most recent emails I'm looking for. Simple enough, especially if I then sort by date. Thank you for explaining this! For A T, > This should work (provided searching is configured for the constituent > groups). it doesn't work but I don't think it's the searching element, or maybe it is. I get an error with the following [elided] backtrace: Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p nil) #f(compiled-function () #)() gnus-summary-highlight-line() gnus-summary-prepare-threads((... ... ... ... ... ... ... ... ... ... ... ... ... ... ...)) gnus-summary-prepare() gnus-summary-limit((143 154 165 174 176 189 192 190 191 193 231 232 233 253 255 250 259 262 245 241 240 218 227 205 213 204 248 197 185 178 221 224 177 168 169 163 194 196 198 199 201 202 143 154 165 174 176 189 192 190 ...)) gnus-summary-limit-include-thread("..." nil) gnus-summary-refer-thread() nnselect-request-thread([4887 "..." ...]) gnus-request-thread(...) gnus-summary-refer-thread(nil) funcall-interactively(gnus-summary-refer-thread nil) command-execute(gnus-summary-refer-thread) The thread I want is there but there are also many other articles. The particular thread has 4 articles in it. If I ask for the thread starting in the right group, I get those articles that are in the thread in that group. Any suggestions? I can try without compiled code to see, if you wish? And, yes, using nnselect, i.e. a more up to date code base for this functionality, is bound to be helpful.
