• v1.5: eZ Platform 1.7LTS & 1.13LTS (bundled out of the box) with Solr 6.x or 4.10.4 (recommended: 6.6 which is an LTS, and certain features only work on Solr 6)
• v1.0.x: eZ Publish Platform Enterprise 5.4.5+ (optional, not as feature rich but helpful for scaling filtering queries) with Solr 4.10.4

Overview of features

by default, for location search available as of v1.3 with Solr 6.x), and as of Solr Search Engine v1.5

Install

For how to install and configure see:

• eZ Platform: https://doc.ezplatform.com/en/latest/guide/solr/
• eZ Publish Platform 5.4.x: https://doc.ez.no/display/EZP/Solr+Search+Engine+Bundle

Testing locally

For Contributing to this Bundle, you should make sure to run both unit and integration tests (from ezpublish-kernel repo).

1. Setup this repository locally

   git clone git@github.com:ezsystems/ezplatform-solr-search-engine.git solr
cd solr
composer install

   At this point you should be able to run unit tests:

   php vendor/bin/phpunit --bootstrap tests/bootstrap.php

2. Get & extract Solr

   E.g. one of the following:

   • Solr 6.6.5

3. Configure Solr (single core)

   Note: See .travis.yml and bin/.travis/init_solr.sh for multi core setups

   # Solr 6
cd solr-6.6.5
mkdir -p server/ez/template
cp -R /lib/Resources/config/solr/* server/ez/template
cp server/solr/configsets/basic_configs/conf/{currency.xml,solrconfig.xml,stopwords.txt,synonyms.txt,elevate.xml} server/ez/template
cp server/solr/solr.xml server/ez
## Modify solrconfig.xml to remove section that doesn't agree with our schema
sed -i.bak '//,/<\/updateRequestProcessorChain>/d' server/ez/template/solrconfig.xml

   Note that Solr Bundle does not commit changes directly on repository updates,
   which can lead to issues of content not showing up in the index. You can control this by adjusting autoSoftCommit (visibility
   of change to search index) and autoCommit (hard commit, for durability and replication) values in solrconfig.xml.

   Example of working solrconfig.xml settings that you can use to tune for your needs, change from defaults is on autoSoftCommit from -1 (disabled) to 20ms:

   
${solr.autoCommit.maxTime:15000}
false



${solr.autoSoftCommit.maxTime:20}


   You may also use the command line tool bin/generate-solr-config.sh to generate the Solr 6 configuration instead of these instructions.
   This is particular convenient if deploying to eZ Platform Cloud (Platform.sh), but can also be used for on-premise installs.

   The script should be executed from the eZ Platform root directory, run the following for more info:

   ./vendor/ezsystems/ezplatform-solr-search-engine/bin/generate-solr-config.sh --help

4. Start Solr

   # Solr 6
cd solr-6.6.5
bin/solr -s ez
## You'll also need to add cores on Solr 6, this adds single core setup:
bin/solr create_core -c collection1 -d server/ez/template

5. Run integration tests

   export CORES_SETUP="single"
php -d memory_limit=-1 vendor/bin/phpunit --bootstrap tests/bootstrap.php -vc vendor/ezsystems/ezpublish-kernel/phpunit-integration-legacy-solr.xml
