Deployment Guide
Data
Data of format .html, .pdf, .docx or .doc are crawled with Heritrix.
They are too large (>20G) and thus not included here, but can be provided upon request.
Preprocessing
To preprocess files under the <dir> directory, run:
cd preprocess
pip install -r requirements.txt
python DocParser.py <dir>
For each file with path <path>, it outputs a processed JSON file <path>.json.
Backend
First build the index by running java -jar backend/out/artifacts/Indexer_jar/SearchTHU.jar <data_dir> <index_dir>
Then put backend/out/artifacts/SearchTHU_war/SearchTHU_war.war at webapps/ of the Tomcat directory, and then start the Tomcat service.
The API path is http://hostname:port/SearchTHU_war/. See the API details at doc/api.md.
Frontend
To start the frontend service:
cd frontend
npm install
npm start
And then go to http://localhost:8080 to start using the application.
