Hi Everyone

I am working on a blog type project where I need to set up search for articles.
I am using sql server and asp.net.

I have set up search using article name and some keywords or tags related to the article.

My issue is how to set up keywords or tags list for a particular article

What I have tried:

What I have done currently is

srno | articlename | description | keywords
1 | abc | complete article text | some relevant keywords

A table with the above columns where articlename and keywords or tags will be searchable.
I also separated all keywords or tags with a delimiter ","

The keyword list is 4-5 keywords or tags per article. Max 10 keywords or tags per article.
Is it advisable to use keywords or tags in the blog table columns

Please advise

Thankyou
