I have used ? and ?? as placeholders for problematic names in CIVICRM records and was searching for them via Full Text Search in All Tables. This returned ok on different tabs for returns in Contacts, Activites and Events. However, when i click "View all results for contacts" under contacts and was brought to a view for all relevant return under contacts, hitting NEXT will yield the Network Error dialog. The ONLY_FULL_GROUP_BY mode is turned off in mysql so it might not be related to that issue. Any ideas?
This doesn't seem to affect alphanumeric search that doesn't have "?"
