        stores data in a huge directory structure, where each character in
        each word encountered has its own directory (along with any word
        that starts with the same characters up to and including the character)
        
        indexing 'foo' and 'frob' will generate the following dir structure::

          /f/o/o/data
            /r/o/b/data

        creating a dir this way makes that searching is very fast, but indexing
        is relatively slow and creates a large dir

        supported are simple searches on multiple words, using 'and' or 'or
        behaviour, not supported is anything else (so no wildcards, etc.)
