Fuzzy (n-gram) matching support in streaming mode

[Alexander-Mark]

Is your feature request related to a problem? Please describe.
When setting gram matching in a field of a doc that uses streaming mode, the following warning is given:
n-gram matching is not supported for streaming search

Describe the solution you'd like
For streaming mode to support n-gram matching.

Describe alternatives you've considered
We are using substring matching in streaming mode as an alternative.

Additional context
Fuzzy search would be nice to have in those cases where high recall (eg misspellings) or CJK search is a priority in apps using streaming mode.
