System Design Practice Problems to get the job faster

Search engines are built to help users find relevant resources based on an inputted search query. In our case, our search engine needs to scan, organize and serve relevant urls to users in a timely manner.

Most search engines require us to organize the search data in a way that allows users to quickly get their results, and ours is no exception. The secret to this problem is understanding that we need to preprocess the data to make it more easily searchable.

Functional Requirements

  • 10 relevant results should be returned for each query if they exist
  • When a user clicks on a result they should be sent to the page
  • A "good match" is when a url contains a specific keyword
  • Searches can only consists of a single keyword
  • All grammatical tenses should map back to the same base words
  • All "stop words"( a, an, you, or ,etc.) should not be included in the index
  • Urls should be checked daily for updates
  • Urls do not need to be ranked off of any relevancy
