Description

The current code for LuceneDictionary will always skip the first word of the TermEnum. The reason is that it doesn't initially retrieve TermEnum.term - its first call is to TermEnum.next, which moves it past the first term (line 76).
To see this problem cause a failure, add this test to TestSpellChecker:
similar = spellChecker.suggestSimilar("eihgt",2);
assertEquals(1, similar.length);
assertEquals(similar[0], "eight");

Because "eight" is the first word in the index, it will fail.
