How to search on ANI field with using this format MCU.*.SUB

I have an account number field (ANI) and I know only MCU and SUB values. I tried to search using this format. MCU.*.SUB (123456.*.987). I want to get all all records with that MCU and SUB.

But it does not work. Do you know how I can search using this format? I used databrowser but it removed the * character.

Thanks
