Some times I have an torrent with 1 seed, and this seed leave the torrent, now I have 0 seed, and I force DHT search, and Tixati find any seed, I force again and again 4 or 5 times, and sometimes I get 2 or 3 seeds. So is fine an setting to choose how much times to do DHT Searchs when used manual way. Because in my experiences, many tests, force DHT many times absolutely have another result.
