Turning on Lemmatization or Query expansion

In the "main.py" file there will be code as follows

def main():
    SearchEngineIns = SearchEngine(True)
    SearchEngineIns.search()

To change to Lemmatization , set the true value to false.

def main():
    SearchEngineIns = SearchEngine(False)
    SearchEngineIns.search()

Then delete the data folder and run the program.

Query Expansion

To enable query expansion go the the main function in main.py

def main():
    SearchEngineIns = SearchEngine(True)
    SearchEngineIns.search()

Add another paramter with the value of true to the Search engine initiatior

def main():
    SearchEngineIns = SearchEngine(True,True)
    SearchEngineIns.search()

Then re-run the program
