I have some issues with a custom text field, containing string like "week-2010-11-15", "week-2010-11-22", etc.
query ( weekField ~ "week" ) returns issues, while ( weekField ~ "2010" ) does not. Also, query ( weekField ~ "week-2010-11-15" ) returns all issues with "week" in this field, no matter what numbers are after.
Seems like really strange behavior. How it is expected to search for numbers in a text field then?
