Record counts on VIVO's index pages are obtained using the same type of Solr query.

How is Solr created and configured?

The VIVO distribution includes a copy of Solr WAR file. When VIVO is installed the Solr WAR file is deployed to Tomcat as a web application.

The behavior of Solr depends extensively on its configuration files. These are stored in a directory that is called the Solr Home directory. In the standard VIVO installation, this is the solr sub-directory in the VIVO Home directory. When VIVO is installed, the Solr configuration files are copied to the Solr Home directory. When VIVO runs, the Solr search index is built inside the Solr Home directory.

If you are installing VIVO in a servlet container other than Tomcat, or if you are installing Solr in a separate servlet container, you will need to tell Solr how to find its home directory. See the instructions in Building a VIVO distribution for other servlet containers.

  • When an individual is added/edited/deleted, Solr is given the new information and updates the index.
  • Sometimes the index must be rebuilt
    • Most commonly, after an ingest, since some of the ingest mechanisms bypass the usual VIVO framework
      • It would be too slow to update the Solr index on each new statement from the ingest
      • Working to add a search-aware ingest method, which Harvester or other tools could use.

    • A rebuild is done on the side, then replaces the previous index, and Solr switches to the rebuilt one.

    • send it requests to
      • search
      • add, update, or delete records
