I randomly generated an 8 character alphabetical (all lower case) password "jraxxhwr". According to keepass it has 32 bits of entropy, but the entropy should be 26^8 = 37.6 bits because the search space is all 8 character letter permutations. There's no way you can reduce the search space from 37.6 bits to 32 bits unless you have an oracle that says which characters I used.
