The mailing list for listmasters using Sympa

["Widerski, Betty" <address@concealed>]

Hi -

 

I’m seeing perhaps inconsistent behavior when searching a large list’s subscribers for all addresses in a subdomain. For example,

               - I have a list of 2000 subscribers

              - about half (900) have the address form “@class2023.college.edu”

               - I want to purge those, so Search “class2023”

               - I’m told how many it finds, but it doesn’t display them, saying “Selection too wide, unable to display selection”

               - I do some smaller searches, like “d@class2023” - these work, but only if the result is less than about 50, otherwise still “Selection too wide”

               - I export the subscribers, use other methods to remove the “class2023” addresses, and also some 950 “class2024” subscribers. I then delete ALL 2000 subscribers in the list (500 at a time) and subscribe my smaller set of remaining addresses - 150.

               - I do a search on the smaller subscriber list that results in more than 50 selections (137) - this does NOT tell me “selection too wide”

 

Please help me to understand what is limiting the search selection display - is it that Sympa can’t search well in really large subscriber sets? Is there a parameter I can change? I’d like to wipe graduated subscribers from lists in which they aren’t the only subscribers.

 

Thanks

Betty
