This is similar to ClassicFilter that removes 's from the end of words. But ClassicFilter is useful for English language only and has nothing to do with Turkish. Because it only removes 's and 'S. In Turkish different character sequences may come after an apostrophe. e.g. 'nin, 'a, 'nin, 'ü etc.
In Turkish, apostrophe is used to separate suffixes from proper names (continent, sea, river, lake, mountain, upland, proper names related to religion and mythology). For example Van Gölü’ne (meaning: to Lake Van).
