The maximum corrections to be returned per suggest text token.
`suggest_mode`::
The suggest mode controls what suggestions are
included or controls for what suggest text terms, suggestions should be
suggested. Three possible values can be specified:
** `missing`: Only suggest terms in the suggest text that aren't in the
index. This is the default.
** `popular`: Only suggest suggestions that occur in more docs then the
original suggest text term.
The suggest mode controls what suggestions are included on the suggestions
generated on each shard. All values other than `always` can be thought of
as an optimization to generate fewer suggestions to test on each shard and
are not rechecked at when combining the suggestions generated on each
shard. Thus `missing` will generate suggestions for terms on shards that do
not contain them even other shards do contain them. Those should be
filtered out using `confidence`. Three possible values can be specified:
** `missing`: Only generate suggestions for terms that are not in the
shard. This is the default.
** `popular`: Only suggest terms that occur in more docs on the shard then
the original term.
** `always`: Suggest any matching suggestions based on terms in the
suggest text.
