Punctuation is not indexed, but future versions might use it for phrasal search.
Searching a word with a comma will be unsuccessful because the comma is used as any other character
together with other punctuation marks.
A dash "-" is a common character, except placed in the beginning of a word that is not quoted
(boolean search). Words with a dash can be searched and indexed. Alkaline can search and index numbers
and words with digits.
Accentuated characters, such as in French, are translated into respective variants (é to e, à to a, etc.)
at both search and index. Multilingual servers using Alkaline might have this feature removed to enable searching
of Russian text for example.
