Code Index with Solr

This guide provides a step-by-step walkthrough on setting up a new code search index as part of LASSO's executable corpus.

Important: Possible security risks are not taken into consideration, so do not expose your instances without proper configuration and security measures.

Quickstart Guide (Docker)​

Prerequisites​

This guide assumes that:

  • A working Docker installation is present on the local machine. For more information, see docker.
  • The official Solr image from Docker Hub (see https://hub.docker.com/_/solr) is used to run the latest version of Solr.

Step-by-Step Instructions​

  1. Create a directory for Solr index:
mkdir lassoindex
  1. Set ownership and permissions for Solr user:
sudo chown -R 8983:8983 lassoindex
  1. Run a new Solr container with a custom index:
docker run -d -v "$PWD/lassoindex:/var/solr" -p 8983:8983 --name lasso_solr_quickstart solr solr-precreate lasso_quickstart
  1. Verify the container is running:
docker ps -a

Alternatively, open your web browser and load Solr's dashboard at http://localhost:8983/.

Update the schema of your newly created index (Optional)​

This step assumes that your Solr instance is running on localhost on port 8983.

  1. Set the path to LASSO's repository:
export LASSO_REPO=/my/path/lasso/repository
  1. Copy LASSO document schema to your index:
sudo cp $LASSO_REPO/doc/solr_config/managed-schema* lassoindex/data/lasso_quickstart/conf/
  1. Set ownership and permissions for Solr user (again):
sudo chown -R 8983:8983 lassoindex/data/lasso_quickstart/conf/
  1. Reload the index to load the new schema:
curl -vvv "http://localhost:8983/solr/admin/cores?action=RELOAD&core=lasso_quickstart"

Alternatively, open your web browser and load Solr's dashboard to reload the index using 'Core Admin' at http://localhost:8983/.

Schema Files​

The schema files are located in solr_config.
