Is it possible to parse the search string?

Question

Parsing

I am doing a home project for myself. The essence of the project is to make a smart search. That is, by entering a query into the search bar, for example #freshpotatoes, the query will be automatically filled in on sites such as instagram and pinterest, and display the answer on my page.
And I faced such a task:
Is it possible to parse the search string and display its answer on the page? What is the best way to do this?
I have never come across parsers, and the search for this resource did not bring me the desired results.

Answer 1

It is better to do this through the services API, for example, instagram.com/developer/, https://developers.pinterest.com/. To do this, you need to create a developer account, understand the documentation. Next, you make a small web application (for example, on Ruby On Rails) that will call API methods of external systems, and you can process the results as you want (Ruby is well suited for word processing).
