Take a look at SpanFirstQuery. Perhaps you would need implement a
SpanLastQuery too.
Perhaps the easiest way about it would be a RegexQuery that looks
something like this: "^the$"
The RegexQuery won't work in this case, as it is only matching on
terms, not original field values. So it'd still pick up other titles
with "the" in them (provided stop words were not removed).
If you need exact matching on original value, the easiest way is to
index that value without tokenization (perhaps lowercasing though).
Unless someone has some other tricks I'm not aware of, that is.
