CLI Docs Search (tf-idf) Engine

This program implements a Command Line Interface (CLI) document search engine based on the Term Frequency-Inverse Document Frequency (tf-idf) algorithm. It searches for the occurrence of specific terms within documents and ranks them based on their relevance.

Features

• Search Functionality: Enter a term or phrase to search for within the documents.
• tf-idf Calculation: Calculates tf-idf scores for the searched terms across documents.
• Sorting: Sorts documents based on tf-idf scores.
• Document Viewing: Displays the path of the most relevant document containing the searched term.
• Continuous Search: Allows for continuous searching without exiting the program.

Usage

1. Input Term to Search: Enter the term or phrase you want to search for.
2. Results Display: View the tf-idf scores for each document containing the searched term.
3. Document Viewing: Access the most relevant document by clicking on the displayed path.

How to Run

To run the program:

1. Compile the code using a C compiler.
2. Execute the compiled program.
3. Follow the on-screen instructions to search for documents.

Requirements

• C compiler (e.g., gcc)
• Standard C libraries (assert.h, stdio.h, stdlib.h, dirent.h, string.h)

Example

$ ./search_engine
> Input term you want to search:
> algorithm

Notes

Make sure the documents you want to search are located in the specified directory ("a\" in this case).
