Is any of the methods for searching VFields except the regex one case sensitive? I've been using VField.FindValueAsArraySet for a long time. One user now has case sensitive data. Regex for sure will be slower.
I guess you have changed some collation settings for db/table/field to make searches case-insensitive - right?
And now you need to do the case-insensitive search?
Probably the simplest way is to change the settings back temporarily?
