Explained the return type of strdist(), since it's different from the commo=
n Levenshtein implementation.

   1. ngram - The NGramDistance, if specified, can optionally pass in the n=
gram size too.  Default is 2.
   1. FQN - Fully Qualified class Name for an implementation of the StringD=
istance interface.  Must have a no-arg constructor.

+ This function returns a float between 0 and 1 based on how similar the sp=

  <!> [[Solr1.4]] Causes it's function query argument to derive it's values=
 from the top-level IndexReader containing all parts of an index.  For exam=
ple, the ordinal of a value in a single segment will be different from the =
ordinal of that same value in the complete index.  The ord() and rord() fun=
ctions implicitly use top() and hence ord(foo) is equivalent to top(ord(foo=
)).
