Add features to the API

Currently, all the API can do is to search an exact name/alias in the database and return its meaning and translations.
We need more features, such as:
- Search (`/search/:term`) - Should return a list of matches by a partial term (Search in both aliases/names)
- Get translation (`/:name/:language`) - Should return the translation of `:name` in `:language`

Anything else you can think of :)

You can easily run the API just by cloning the repo and run `npm install && npm start`, then you should be able to browse to `http://localhost:3000` and see the API is running.
Your clone will connect to the actual production database, however the user supplied there is only able to `select`, and is limited by its number of queries per hour.

If you need help or have any ideas, feel free to comment here.

Clone the repository, run npm install && npm start, and inspect the existing API routes and database access. Implement the specified partial-name search and name-language translation endpoints, then verify they return the requested matches and translations while respecting the production database query limits.
