collective.solr integrates the Solr search engine with Plone.

Apache Solr is based on Lucene and is the enterprise open source search engine. It powers the search of sites like Twitter, the Apple and iTunes Stores, Wikipedia, Netflix and many more.

Solr does not only scale to any level of content, but provides rich search functionality, like faceting, geospatial search, suggestions, spelling corrections, indexing of binary formats and a whole variety of powerful tools to configure custom search solutions. It has integrated clustering and load-balancing to provide a high level of robustness.

collective.solr comes with a default configuration and setup of Solr that makes it extremely easy to get started, yet provides a vastly superior search quality compared to Plone’s integrated text search based on ZCTextIndex.

Detailed Documentation

A full Documentation of the Solr integration of Plone could be found on collectivesolr.readthedocs.org.

Installation & Configuration

Download the latest default Solr configuration from github:

$ wget https://github.com/collective/collective.solr/raw/master/solr.cfg
$ wget https://raw.githubusercontent.com/collective/collective.solr/master/solr-4.10.x.cfg

Extend your buildout to use those files and make sure collective.solr is added to the eggs in your instance section. Your full buildout file should look something like this:

[buildout]
parts += instance
extends =
    https://dist.plone.org/release/4.3.8/versions.cfg
    solr.cfg
    solr-4.10.x.cfg

[instance]
recipe = plone.recipe.zope2instance
http-address = 8080
user = admin:admin
eggs =
    Plone
    collective.solr

[versions]
collective.recipe.solrinstance = 5.3.2

After saving this to let’s say buildout.cfg, the buildout can be run and the Solr server and Plone instance started:

$ python bootstrap-buildout.py
$ bin/buildout
...
$ bin/solr-instance start
$ bin/instance start

Next you should activate the collective.solr (site search) add-on in the add-on control panel of Plone. After activation you should review the settings in the new Solr Settings control panel. To index all your content in Solr you can call the provided maintenance view:

http://localhost:8080/plone/@@solr-maintenance/reindex

Solr connection configuration in ZCML

The connections settings for Solr can be configured in ZCML and thus in buildout. This makes it easier when copying databases between multiple Zope instances with different Solr servers.

Example:

zcml-additional =
    <configure xmlns:solr="http://namespaces.plone.org/solr">
        <solr:connection host="localhost" port="8983" base="/solr/plone"/>
   </configure>

Current Project Status

The code is used in production in many sites and considered stable. This add-on can be installed in a Plone 4.3 (or later) site to enable indexing operations as well as searching (site and live search) using Solr. Doing so will not only significantly improve search quality and performance - especially for a large number of indexed objects, but also reduce the memory footprint of your Plone instance by allowing you to remove the SearchableText, Description and Title indexes from the catalog as well as the lexicons if no other indexes are using them.

In large sites with 100000 content objects and more, searches using ZCTextIndex often taken 10 seconds or more and require a good deal of memory from ZODB caches. Solr will typically answer these requests in 10ms to 50ms at which point network latency and the rendering speed of Plone’s page templates are a more dominant factor.

Plone Compatibility

collective.solr works with Plone 5.2 and Plone 6.

Python Compatibility

collective.solr works with Python 3.8 and 3.9. Older versions might still work but we do not test them.

Solr Compatibility

collective.solr works with Solr 7,8, and 9. Older versions might work as well but we do not test them.

• Refactor ISearch. The method buildQuery has been replaced with buildQueryAndParameters. Responsabilities have been divided in the search view and the utility, now they are all in the search utility. If you used the method before, please analyse the changes in collective.solr.dispatcher:solrSearchResults from 4.0.3 to 4.1.0 You can probably benefit from the changes. [do3cc]

• Add “actual_result_count” attribute to SolrResponse to emulate catalog attribute. [cekk]

• Sort arguments in buildQuery to get a stable ordering for test output. [hannosch]

• Solr facet queries on unknown fields will now raise a SolrException. [hannosch]

• Update example configuration to Solr 3.5. [hannosch]

• Fix control panel adapter to save the search_pattern as utf-8. [ggozad]

3.0b4 - 2011-11-10

• Revert unrestrictedSearchResults change, as it breaks additional catalogs, like the membrane catalogs. [hannosch]

3.0b3 - 2011-11-09

• Made maintenance sync view compatible with latest internals of field indexes. [hannosch]

• Also dispatch unrestrictedSearchResults to the Solr server. https://github.com/Jarn/collective.solr/issues/5 [reinhardt, hannosch]

• Tweak search form to better match sunburst proportions. [elro]

3.0b2 - 2011-10-05

• Facet titles can now be provided by specialized vocabularies. Register a named IFacetTitleVocabularyFactory utility and it’ll be used to get a vocabulary for the facet field with the same name. [mj]

3.0b1 - 2011-09-27

• Extend the wildcard search term manipulation to do Unicode to ascii folding, to keep up with the default field settings of the text field. [hannosch, mj]

3.0a5 - 2011-09-26

• Don’t treat search terms ending in numbers as simple, as Solr doesn’t deal with wildcard searches for numbers. [hannosch]

• Include CMFCore’s permissions.zcml. [witekdev, hannosch]

3.0a4 - 2011-08-22

• Fixed bug in extender.searchwords indexer - terms need to be lowercased explicitly. [hannosch]

3.0a3 - 2011-08-22

• Fixed handling of intra-word hyphens to be taken literally instead of being interpreted as syntax for text fields. [hannosch]

• Explicitly require Plone 4.1 / Zope 2.13. [hannosch]

• Depend on the new c.indexing 2.0a2. [hannosch]

• Added an archetypes.schemaextender dependency and register two fields for all objects providing IATContentType. showinsearch is a boolean field that can be used to hide specific content items from search results. searchwords is a lines field, which lets you specify words that an object should be found under. [hannosch]

• Standardize on solr as the i18n domain. [hannosch]

3.0a2 - 2011-07-10

• Adjust munin configs for query cache handlers to c.r.solrinstance 3.5 changes using FastLRUCache. [hannosch]

• Added tests for splitting words on : and -. [hannosch]

• Update example configuration to Solr 3.3. [hannosch]

• Add getRID and _unrestrictedGetObject to our flare implementation. [hannosch]

• Added documentation on setting up a master-slave configuration using the SolrReplication support. [hannosch]

• Adjust tests to work with latest collective.recipe.solrinstance = 3.3 and its new ICU-based text field. [hannosch]

3.0a1 - 2011-06-23

Upgrade notes

• Changed the names of the indexes used to emulate the path index. You need to adjust your schema and rename physicalPath to path_string, physicalDepth to path_depth and parentPaths to path_parents. This also requires a full Solr reindex to pick up the new data. [hannosch]

Changes

• Added object_provides index to example schema, as it’s used in the collection portlet to find collections. [hannosch]

• Rewrote the maintenance/sync method for more performance, dropped the optional path restriction from it and removed the cache argument. It should be able to sync datasets in the 100,000 object range in the matter of a couple minutes. [hannosch]

• Changed the maintenance/reindex method to only flush data to Solr but not commit after each batch. Instead we only commit once at the end. You should configure auto commit policies on the Solr server side or commitWithin. [hannosch]

• Adjusted the mangleQuery function to calculate extended path indexes from the Solr schema instead of hardcoding path. If you have any additional extended path indexes, you need to provide indexers with the same three suffixes as we do ourselves in the attributes module for the path index and add those to the Solr schema. [hannosch]

• Added documentation on Java process, monitoring production settings and include a number of useful munin plugin configurations. [hannosch]

• Updated example config to include production settings and JMX. [hannosch]

• Updated example config to collective.recipe.solrinstance 3.1 and Solr 3.2. [hannosch]

2.0 - 2011-06-04

• Updated readme and project description, adding detailed information about how Solr works and how we integrate with it. [hannosch]

2.0b2 - 2011-05-18

• Added optional support for the Lazy backports founds in catalogqueryplan. [hannosch]

• Fixed patch of LazyCat’s __add__ method to patch the base class instead, as the method was moved. [hannosch]

• Updated test config to Solr 3.1, which should be supported but hasn’t seen extensive production use. [hannosch]

• Avoid using the deprecated five:implements directive. [hannosch]

2.0b1 - 2011-04-06

• Rewrite the isSimpleSearch function to use a less complex regular expression, which doesn’t have O(2**n) scaling properties. [hannosch]

• Use the standard libraries doctest module. [hannosch]

• Fix the pretty_title_or_id method from PloneFlare; the implementation was broken, now delegates to the standard Plone implementation. [mj]

2.0a3 - 2011-01-26

• In solr_dump_catalog correctly handle boolean values and empty text fields. [hannosch]

2.0a2 - 2011-01-10

• Provide a dummy request in the solr_dump_catalog command. [hannosch]

2.0a1 - 2011-01-10

• Handle utf-8 encoded data correctly in utils.isWildCard. [hannosch]

• Gracefully handle exceptions raised during index data retrieval. [tom_gross, hannosch]

• Added zopectl.command entry points for three new scripts. solr_clear_index will remove all entries from Solr. solr_dump_catalog will efficiently dump the content of the catalog onto the filesystem and solr_import_dump will import the dump into Solr. This can be used to bootstrap an empty Solr index or update it when the boost logic has changed. All scripts will either take the first Plone site found in the database or accept an unnamed command line argument to specify the id. The Solr server needs to be running and the connection info needs to be configured in the Plone site. Example use: bin/instance solr_dump_catalog Plone. In this example the data would be stored in var/instance/solr_dump_plone. The data can be transferred between machines and calling solr_dump_catalog multiple times will append new data to the existing dump. To get Solr up-to-date you should still call @@solr-maintenance/sync. [hannosch, witsch]

• Changed search pattern syntax to use str.format syntax and make both {value} and {base_value} available in the pattern. [hannosch]
