Very grateful for your quick review!
Let me explain why this is important.
Buyers enter into the search keywords in various ways, and not only in the way they are indicated in the title or description. And just in the field of keywords you can list all these options and synonyms.
And to add these all variants of keywords to the description is terrible! They are not needed there, they interfere with customers and display a lot of unnecessary and useless text.
Thanks for the link, but the component you offer does not fit. It is necessary that there was not a choice of tags, namely that the search module was able to search by keywords.
Introduce, please, in the next version, search by keywords and meta description.
