I created a custom field of type LongText to hold a ticket number from a vendor. I created an issue and entered the value 4615713488 in the field. I made it searchable and filterable. However, when I search for the value 4615713488 from the search box on the top, it throws an Internal Server Error. This is the dump from the production.log:

It appears to me that the system thinks it is an issue number because the value is numeric. However, it I put it in double quotes like this "4615713488" it returns the correct ticket. I cannot count on my users knowing to do that when searching for something.

Any advice?
