* Text analyzers, for differentiating passages to improve ranking.
*
* Scorers measure some aspect of the answer or passage, possibly in relation
* to the question. Every scorer must return a primitive double.
* <p>
* Remember that the purpose of a scorer is not to provide a perfect rank on
* it's own, only to differentiate "good" and "bad" passages in some meaningful
* way. As such, the scale and sign are not very important.
