Create Release v4.4.0

[17sushmita]

Please create a release to publish these unreleased changes -

• Adds MatchedQueries field to SearchHit #663
• Add Highlight field to SearchHit struct #654

I'm using this library in my project and need these features quickly

Thanks

I can take care of this, need a bit of help from other maintainers with merging #667 and possibly others.
