There's many ways to accomplish this use case so I will just mention a couple

Tumblr

Follow the steps from Use Case 2 to execute a search. After you have a list of results displayed in a table, choose a post that interests you. Each post has a "View Blog Info" button. Clicking this button will make an additional call so that you can retrieve some information about the blog including the number of posts written, if they allow questions, their avatar picture, and more! If you scroll to the bottom of the page, you will also be able to look at some recent posts written by the blog as well as a link to the post on Tumblr (this will cause you to leave the site unless you open it in a new tab).

Database Implementation

Follow the steps from Use Case 2 to execute a search. If you search by Travel, you should see multiple posts appear. Click on any one of the post names. This will open up the individual post and display it. It will contain information about the post, including the title, who wrote it, when it was published, how many people have shared it, and the post itself.

If any comments exist on the post, these will also be retrieved when the page is opened and they will display in the comment section.
