===== Upgrade to Solr 8 =====

If your search is configured with ```http://localhost:7070/sme/``` you will need move to Solr 8. After upgrading you will need to run a reindex as data cannot be migrated.

First stop the current search service.

    systemctl stop jetty
    systemctl disable jetty

Change to the ```smestorage``` user.

    su - smestorage

Create container for Solr.

    mkdir /var/www/smestorage/containers/solr
    cat > /var/www/smestorage/containers/solr/docker-compose.yml
    version: '3.7'
    services:
      sme_solr:
        image: 'registry.storagemadeeasy.com/sme_solr:8.11.2-6'
        restart: always
        volumes:
          - "/var/solr:/var/solr"
        ports:
          - "127.0.0.1:8983:8983"
          - "127.0.0.1:7070:7070"
        command:
          - solr-precreate
          - sme
          - /opt/solr/server/solr/configsets/sme
        environment:
          - SOLR_HEAP=15360M
    ^D

Create container for PDF Burner if you are using:

    mkdir /var/www/smestorage/containers/pdfburner
    cat > /var/www/smestorage/containers/pdfburner/docker-compose.yml
    version: '3.7'
    services:
      pdfburner:
        image: 'registry.storagemadeeasy.com/pdfburner:5.0.0'
        restart: always
        ports:
            - "127.0.0.1:7071:8080"
    ^D

Exist from the shell as smestorage user and become root again.

Make sure the data folder exists:

    mkdir /var/solr

Pull in the Solr image and start the service

    cd /var/www/smestorage/containers/solr
    docker compose pull
    docker compose up - d
    
To check the service is starting correctly:

    docker compose logs -ft
    
Pull in the PDF Burner image and start the service

    cd /var/www/smestorage/containers/pdfburner
    docker compose pull
    docker compose up - d
    
Change the settings under Site Search Integration to ''http://127.0.0.1:8983/solr/sme/'' as per the configuration above.

For each provider navigate to provider settings and under "Tech Info" select the cog icon "Manage Content Indexing". Select "Reindex".  A background tasks will be created that will reindex the provider.
