Is "Wildcard field type" of "Free and open-Basic 1,2" available for commercial use free of charge?
Is "Free and open -Basic 1, 2" already free for commercial use?
I look forward to hearing from those involved in elasticsearch.
Thank you for reading.
Yes wildcard type is included in Free and Basic.
It is not clear what you mean by commercial use?
I would suggest you taking a look at this post and read the license and FAQs etc.
The Free and Basic version can be used for many use cases... There are exceptions you should read about them.
