Fix: list words starting with lower or upper case

[DumiJDev]

The search is not insensitive case, there is difference between 'b' and 'B', there 'Brasil' and 'brasil' words, in both is the same.

[DumiJDev]

Brasil can be found searching with 'B' in the first page, and brasil can be found in the 229th page searching with 'b'

brasil
