I found that, in the *.tim it not only stores suffixes information, but it also stores information of the current prefix's child nodes' position.Taks terms 'ab1,abc1,abc2‘ for example, for the prefix 'ab', *.tim stores the suffix '1' and the file position of terms starting with prefix 'abc'. I wonder why, because the file position of prefix 'abc' can be got form FST, and prefix 'ab' knows the existence of 'abc',why we store it in the *.tim again? For the speedup of WildCardQuery?
