Using the VLO faceted browser, metadata can be searched and browsed by facet. It consists of three software components: a Solr server with VLO specific configuration, an importer and a web application front end.
Build the project using Maven in the project root, or use the build.sh script, which will use a docker image with the correct version of Java and Maven to build. See the script source for more details.
After a successful deployment and configuration, you should be able to browse to the VLO web app and browse the imported records. You can also run the VLO locally using the docker image (see compose_vlo)
If the VLO is empty, you will need to run an import first.
To run an import, go the bin child directory of the VLO application directory
and run
./vlo_solr_importer.sh
as the appropriate user (e.g. vlouser).
It's advisable to run this in a detached background process (for example using
screen) because an import can take quite a long time depending on the amount
of records to be imported. Also make sure that enough memory is available.
Some VM parameters are configured inside the script.
Some progress information is logged to a file log/vlo-importer.log. It gets
rotated automatically by the import process.
For a fresh import, even when the VLO is not configured to delete all documents from the index first, you can simply remove the contents of the Solr data directory (check server configuration documentation for the exact location).
