Looks like your "field config" is not correct.
In your code, you used the logical AND ( && ) -- rather than the bitwise OR
( | ):
int config = Field::STORE_YES | Field::INDEX_TOKENIZED;
>>> I can see my fields in the index file
To browse your index, you can use a wonderful tool called "Luke". To find
it, just google for: luke lucene
With Luke, I was able to see that :
-- your original code produced an 'empty' index (it had no terms);
-- with the change suggested above -- the index was populated with 3 terms
(nixon, obama, clinton); and your query returned 1 hit in Document ID 0.
Hope this helps.
