Solr integration for Plone

Project description


ftw.solr integrates the Solr search engine with Plone.


Since version 2.0 ftw.solr no longer depends on collective.solr. Instead it provides it’s own Solr integration using Solr’s REST API. Version 2.0 is a complete rewrite and is not compatible with ftw.solr 1.x.

ftw.solr does not try to replace the portal catalog of Plone and does not hook into the catalog’s search function. Instead it provides a search utiltity that must be used explicitly. It’s meant to be used in search forms for fulltext searches while the portal catalog is still in use for things like navigation or folder contents. The goal is to get rid off all fulltext indexes (e.g. ZCTextIndex) in the portal catalog.

ftw.solr requires Apache Solr 7.0 or higher.


Add as dependency

Install ftw.solr by adding it to the list of eggs in your buildout or by adding it as a dependency of your policy package.

eggs +=

Solr installation

To install a Solr server with buildout you can use the ftw.recipe.solr recipe.

recipe = ftw.recipe.solr
cores = mycore

Configure the Solr connection

The connections settings for Solr can be configured in ZCML and thus in buildout. Example:

zcml-additional =
    <configure xmlns:solr="">
        <solr:connection host="localhost" port="8983" base="/solr/mycore"/>

Run buildout

After running buildout and restarting your instance you can install the ftw.solr addon in Plone.


Get the ISolrSearch utility and call the search method to get search results from Solr.

from ftw.solr.interfaces import ISolrSearch
from zope.component import getUtility

solr = getUtility(ISolrSearch)
resp ='SearchableText:foo')

You can get a style result by adapting IContentListing:

from import IContentListing
listing = IContentListing(resp)
