+- Przy concordia searh dodatkowo obliczany ma być zestaw optymalnego pokrycia patternu. Może siłowo? (jeśli przyjąć max dł. zdania 500 tokenów, to nie powinno być źle)
 - Prawdopodobnie długość example w markers będzie potrzebna tylko anubisowi (który, jak się okazuje, jest wolny). Pomyśleć, do czego można wykorzystać markery, bo ich idea wydaje się niezła.
 - Multi-threading?
 - concordia-server (zastanowić się, czy nie napisać CAT-a)
-- wyłączyć stopWords
 - zastanowić się nad empty hash examples (rozwiązanie: w ogóle nie szukać fraz o pustym hashu, rzucać wyjątek).
 - puścić 100% search test na jrc
