- zastanowić się nad empty hash examples

zastanowić się nad optymalizacją:

- unordered_map tmMatchesMap
|

- LCP array

Anubis search się komplikuje! Przy tworzeniu obiektu tmMatches dla przykładu trzeba podać id przykładu, długość patternu i długość przykładu. Dwa pierwsze mamy, ale niestety nie ma skąd wziąć długości przykładu. Pamiętamy tylko offset sufiksu.
