information-retrieval-system's Introduction

Prerequisites to run this project:
1) Python Environment
2) Java IDE like Eclipse to import entire Lucene Folders as Java Projects


Steps for project execution:

NOTE: Execute each file in the exact order as mentioned below.
Execute python file by:
> python file_name.py

Only Lucene model is implemented in Java. To execute it, just import the entire project into Eclipse
> Run project as Java Application
