Problem z ponowym połączeniem

Witam pisze wyszukiwarkę client - server. Wszystko jest ok, wysyłam plik z danymi z klienta do severa tam szukam trafień ale nie mogę odesłać do klienta wyników, ponieważ socket po wysłaniu pliku jest zamknięty i nie mogę drugi raz go otworzyć. Pierwszy raz biorę się za programowanie client-server więc proszę o wyrozumiałość.

Jak mam napisać odsyłanie pliku z wynikami trafień z servera do klienta?? Z góry dzięki za pomoc.
