Can't search contact with only number
Contact search by number has stopped working for a few sites, when searching by only number the system searches by id rather than display/sort name. The system has an external identifier attached to sort/display name which helps the staff to search the contact based on their old legacy number or by contact name. I can see there has been a recent change in Civi which would allow doing a search if the number starts with 0 but it is not the case here.
Is it right to say that force search by id should be a config setting which can be turned off on some systems either via UI or in civicrm.settings.php?
