Product Tags

Hello David,
I hope you are doing well.  I have noticed when I test my product tags that that if I am clicking a ring tag it will bring up other types of jewelry such as brooches.  I had a space between each tag.  So I changed one group to ,no space between each tag and it still happens.  How to correct this?

in the Docs.  Product Tags
If applicable, enter product tags. Useful for search engines, SEO and visitors. Multiple tags to be comma delimited. Example:

Tag One,Tag Two,Tag Three

etc. If a tag is clicked it performs the same action as someone keying a keyword into the search box in your store.

Thank you
