> To account for languages which use binding characters ("fogemorphemes") for composing words the {{HyphenationCompoundWordTokenFilter}} re-checks the dictionary for a candidate with the last character removed when the original candidate was not found. It currently does not re-check against {{minSubWordSize}} in this case. Terms that are one character shorter than {{minSubWordSize}} can be returned.
