> DictionaryCompoundWordTokenFilter: Due to an off-by-one error, a word component placed last in a compound word, will not get a token if its length is equal to the minimal sub-word length.
> Example:
> min sub-word length: 4
> Dictionary: {"alfa", "beta"}
> word: "alfabeta"
> Created tokens: {"alfabeta", "alfa"}
> Expected tokens: {"alfabeta", "alfa", "beta"}
> I have a patch with a testcase that fails on versions 3.1 and 4.0 (probably for everything between as well, and for previous versions), along with a bugfix.
