partially known password how to use this advantage

[GoogleCodeExporter]

What steps will reproduce the problem?
1.so obviously the problem is i'm trying to guess my password
i am aware that my pass was between 18 to 22 characters long
i am aware of some very possible combinations 
password is quite strong but i know all possible characters that had been used
2.therefore i do input this command
truecrack -t /path -k whirlpool -c 'possible characters' -s 18 -m22 -b 1024 -v
but there is just too many combinations i want to narrow it
3.i know hashing algorithm it was whirlpool
4.i know encryption algorithm it was serpent-aes
5.how can i make application to search for password in this form :
{first 4 characters known only 2 combinations}{another 2 characters only two 
combinations}{another 4 characters known}{another 6 characters known but not in 
what order}{another 4 or 3 characters known 8 possible combinations}

What is the expected output? What do you see instead?
all being searched for but takes too long

What version of the product are you using? On what operating system?
kali linux 1.09 kernell 3.14 64bit
truecrack v3.0
