Minor fixes to the `match` query. 

Fixed documentation since the default rewrite method for fuzzy queries is to
select top terms, fixed usage of the fuzzy rewrite method, and removed unused
`rewrite` parameter.

The `prefix_length` and
`max_expansions` can be set in this case to control the fuzzy process.
If the fuzzy option is set the query will use `constant_score_rewrite`
If the fuzzy option is set the query will use `top_terms_blended_freqs_${max_expansions}`
as its <<query-dsl-multi-term-rewrite,rewrite
method>> the `fuzzy_rewrite` parameter allows to control how the query will get
rewritten.
