Because compound suggestions can be very wild, it would be great to be able to limit them to a certain amount of difference from the orginal word.
checking word length difference first, then use levenshtein function to calculate the difference. Longer words should tolerate more diff on suggestions then short ones.
A table in the .aff should specify what limits (length range of source word and max difference) should apply:
MAXDIFF [minlen] [maxlen] [maxdiff]
