> Apache Solr, a modern search engine, seems to be one of the most commonly
> requested feature within the OFBiz community. With my agency, ilscipio, we
> have done several Apache Solr implementations in the past, and we felt that
> we could contribute this feature to the community. Currently, Solr is greatly
> used within syracus.net (our standalone store) and serves to generate the
> categories & search functionalities. From our team mainly Pascal Proulx,
> Jonatan Soto and I were involved in this feature (albeit more having
> contributed to it. We created a standalone component which can be integrated
> into any running ofbiz implementation. It was tested against OFBiz 09.04 -
> 12.04..
> =====================================================
> Solr Component for Apache Ofbiz
> =====================================================
> This document describes the Ofbiz solr component, an Ofbiz
> (http://ofbiz.apache.org/)
> implementation of the Apache Solr search platform
> (http://lucene.apache.org/solr/).
> The solr component includes an Ofbiz service-based wrapper layer to the
> Apache Solr
> webapp queries as well as the native Apache Solr web interface itself.
> Currently, the solr component focuses on Product data.
> Note: This document is a work in progress; information is subject to change.

> -----------------------------------------------------
> 1. Installation
> -----------------------------------------------------
> To install solr in an Ofbiz setting, simply extract the solr directory and
> and sub-folders to the hot-deploy folder.
> Afterward, the solr home system property (solr.solr.home) must be set to the
> value
> hot-deploy/solr manually using one of the following methods:
> * solr.solr.home in batch/script file:
> Add the parameter "-Dsolr.solr.home=hot-deploy/solr" to the Java command
> invocation for ofbiz.jar.
> e.g.:
> "%JAVA_HOME%\bin\java" -Xms128M -Xmx512M -XX:MaxPermSize=512m
> -Dsolr.solr.home=hot-deploy/solr -jar ofbiz.jar
> * solr.solr.home in Ant build configuration:
> In your root Ofbiz build.xml file, add the element "<jvmarg
> value="-Dsolr.solr.home=hot-deploy/solr"/>"
> to the "<java jar="ofbiz.jar"...>" invocation of the appropriate Ant
> target(s) (run, start, run-install, etc.).
> e.g.:
> <target name="start" description="Start OFBiz">
> <java jar="ofbiz.jar" fork="true">
> <jvmarg value="${memory.initial.param}"/>
> <jvmarg value="${memory.max.param}"/>
> <jvmarg value="${memory.maxpermsize.param}"/>
> <jvmarg value="-Dsolr.solr.home=hot-deploy/solr"/>
> </java>
> </target>
> ***
> It may be possible to specify solr home using other methods (JNDI, web.xml),
> but at the time
> of this writing, this was the most reliable method known.
> -----------------------------------------------------
> 2. Configuration
> -----------------------------------------------------
> The solr component can run out-of-the-box without configuration, but many
> files, settings and interfaces allow custom settings. Some of these include:
> * Ofbiz configurations:
> ** System properties:
> *** ofbiz.solr.eca.enabled - Global solr ECA toggling boolean (true/false,
> see Data Indexing)
> ** Config files:
> *** solr/config/solrconfig.properties - Ofbiz solr service behavior control
> *** ofbiz-component.xml - Standard Ofbiz component config
> * Apache Solr configurations:
> ** System properties:
> *** solr.solr.home - Solr home (see Installation)
> ** Config files:
> *** solr.xml - Base solr config
> *** conf/schema.xml - Solr index schema
> *** webapp/WEB-INF/web.xml - Dual Ofbiz/Solr webapp config
> ** Interfaces:
> *** /solr/admin/ - Webapp admin interface (see below)
> ***
> It is possible to set extensive native Solr configuration using
> the admin webapp interface noted above. It should be accessible at the
> address:
> http://localhost:8080/solr/admin/
> (where 8080 is your server's http port)
> Please refer to the Apache Solr documentation for usage of this interface
> and other native Solr configuration details.
> -----------------------------------------------------
> 3. Data Indexing
> -----------------------------------------------------
> The solr component indexes data such as Products into the Apache Solr database
> using services defined in the file:
> servicesdef/solrservices.xml
> The initial indexing may need to be performed or scheduled manually, but
> subsequent indexing
> may be partially or fully automated, though automated methods are disabled by
> default and must be enabled.
> Note that in general, solr services can only successfully run in contexts
> where the solr webapp is
> loaded and accessible.
> There are two methods for indexing data:
> * Index rebuilding service (rebuildSolrIndex):
> The rebuildSolrIndex is the most important data import service. It reindexes
> all Ofbiz Products existing in the system into the solr index.
> rebuildSolrIndex MUST be run
> AT LEAST once after installation and also following any data load operation
> that loads new products using the Ofbiz
> "install" starting mode (run-install, load-demo, etc.).
> To do this, one can simply use the Webtools backend to invoke the service
> manually
> (e.g.,
> /webtools/control/setSyncServiceParameters?SERVICE_NAME=rebuildSolrIndex&POOL_NAME=pool&_RUN_SYNC_=Y)
> or summon the Webtools Job Scheduler.
> Once the initial indexing has been performed, one can then use the Job
> Scheduler to
> invoke rebuildSolrIndex on a regular basis (every hour, every midnight, etc.)
> to update the Solr index.
> * ECAs/SECAs (addToSolr, for Product data):
> Although the rebuildSolrIndex is always necessary for the initial data
> import, one may also
> use ECAs and SECAs to import subsequent data changes automatically at every
> individual data (e.g. Product)
> update instead of running rebuildSolrIndex periodically. This is done by
> defining ECAs or SECAs that
> trigger the addToSolr service.
> The addToSolr service simply accepts a single "instance" parameter, a
> GenericValue. At the time of this writing,
> any entity value having a valid "productId" field designating a Product value
> may be passed; this will trigger reindexing
> for the specific product.
> By default, the addToSolr service implementation (and any service intended
> for use with ECAs) is disabled globally and
> succeeds silently. It can be enabled by setting the "solr.eca.enabled=true"
> in "config/solrconfig.properties".
> This property is provided for easy toggling. It can also be specified on the
> command line or using ant through
> the true/false "ofbiz.solr.eca.enabled" system property (which has priority
> over file-based "solr.eca.enabled") in the same
> way described for the solr home system property (see Installation); this
> allows toggling them per Ant target.
> Some stock/default/example ECAs are provided and are functional once enabled.
> They can be found in:
> entitydef/eecas.xml
> Custom ECAs may also be added to this file, and custom SECAs may be added to
> the file:
> servicedef/secas.xml
> Special care may need to be taken to ensure the addToSolr is not triggered
> during "install" sequences
> (run-install/load-demo) because it requires the solr webapp to be accessible.
> addToSolr will automatically
> attempt to prevent reindexing in cases where the solr webapp is unavailable.
> However, it is possible that
> this behavior results in needlessly prevented reindexing (and thus lost
> updates) in some unknown complex server
> configurations. If this is the case, this behavior can be disabled by setting
> the option
> "solr.eca.useSolrWebappLoadedCheck=false" in the properties file
> "config/solrconfig.properties".
>
> However, if the above useSolrWebappLoadedCheck option is specified, you will
> have to manually disable or comment the
> ECA definitions/services to prevent them from executing during data-load
> operations; the "solr.eca.enabled" property and "ofbiz.solr.eca.enabled"
> system property can be used for this purpose. One easy way is to set
> "solr.eca.enabled=true" in
> the property files and then specify "-Dofbiz.solr.eca.enabled=false" for any
> relevant
> Ant build install/run-install/load-demo targets.
> Note that simply commenting the ECAs/SECAs or preventing their inclusion using
> ofbiz-component.xml may eliminate some service call overhead compared to
> using the property toggling. Ideally,
> a method exploiting ofbiz-component.xml or eecas.xml to prevent ECAs from
> running in inappropriate contexts
> would be ideal; however, at the time of this writing, such a method could not
> be established.
> ***
> To reset and clear the solr index completely, it is sufficient to shut down
> the server and delete the folders:
> solr/data/index
> solr/data/spellchecker
> and any other such folders (must delete the whole folders, not only contents).
> -----------------------------------------------------
> 4. Data Querying
> -----------------------------------------------------
> Solr queries can be done using two methods:
> * Solr Ofbiz services:
> Simply invoke (manually or in code) the query services found in the file:
> servicesdef/solrservices.xml
> These include solrProductsSearch, solrKeywordSearch and others. Note that in
> general,
> solr services can only successfully run in contexts where the solr webapp is
> loaded and accessible.
> * Solr native admin webapp interface:
> One can also perform native Solr queries and diagnostics using the standard
> admin interface, accessible as described under Configuration. Please refer
> to the Apache Solr documentation for usage of this interface.
> -----------------------------------------------------
> 5. Implementation Concerns
> -----------------------------------------------------
> * The structure of the solr/webapp directory closely mirrors the contents of
> the solr.war
> distribution; however, please note that it contains some Ofbiz-specific
> modifications such
> as those found in web.xml. The same is true for other folders such as
> solr/conf. Therefore,
> any library updates must be done with care to preserve these modifications.
> -----------------------------------------------------
> 6. Known Bugs, Limitations and Issues
> -----------------------------------------------------
> * In general, solr services can only successfully run in contexts where the
> solr webapp
> is loaded and accessible.
> * ECA indexing may be problematic due to data loading and unknown complex
> server configurations;
> various toggling options are provided to work around this issue (see Data
> Indexing for details).
> In the future - and ideally - this could be addressed using
> ofbiz-component.xml (or eecas.xml) directives.
> * The indexing services often produce the log warning "Problem reading
> product features" due to their
> use of the stock Ofbiz getProductFeatureSet service.
> ***
> Please report any other issues encountered. Thank you.
