This Text Retrieval system indexes files located in src/main/resources/data/ and allows you to search through them using a single query. This performs the Porter2 Stemming Algorithm on each word in the files and in the input to group like words (such as generous and generosity).

1. Put .txt files into src/main/resources/data/ that you would like to search through
2. Add or remove words from src/main/java/process/stoplist.txt to have them ignored. Stop words do not contribute to the cosine normalization.
3. Run src/main/java/index/Invert.java to index the files
4. Run one of these files
   • Run src/main/java/search/Driver.java to run a normal query
   • Run src/main/java/search/VSMTester.java to perform cosine normalization and be returned the top 1000 documents
5. Your query's results should be saved in the top level directory

1. NOT: NOT x returns all documents that do not contain x
2. AND: x AND y returns all documents that contain x and y
3. OR: x OR y returns all documents that contain x, y or both
