Use the Index

1. Delete the hardcoded "merida" search test from your build command.
2. Add a load() method to your InvertedIndex class. It should load the index and docmap from disk using the pickle module's load function.
   • Use cache/index.pkl for the index
   • Use cache/docmap.pkl for the docmap
   • It should raise an error if the files don't exist.
3. Update your search command to load the index from disk. If it doesn't exist, print an error message and exit.
4. Remove the logic that loops through every query and every movie.
5. Instead, iterate over each token in the query and use the inverted index to get matching documents.
   • Stop searching once you have 5 results.
   • Print the resulting document titles and IDs.

Run and submit the CLI tests.
