Revolutionize your Drupal search experience

This module integrates Drupal with the Apache Solr search platform. Solr search can be used as a replacement for core content search and boasts both extra features and better performance. If you're looking for Apache Solr integration, this is possibly the best option available.


Faceted Search
Faceted search is supported if you use the facet API module. Facets will be available for you ranging from content author to taxonomy to arbitrary fields.
More like this
Relevant content blocks ("More like this" blocks) can be added to any node page. The block will show you relevant nodes and/or nodes similar to the one your site-visitor is viewing. The analysis happens realtime in Solr
Search Pages
Multiple search pages with optionally customized search results, layout and others
Search Environments
Add multiple Solr Search cores and query them so you can optimally connect to the one of your choice. Ideal to have multiple facet configurations.
Range Queries
These query types, in combination with Facet Api Slider, delivers a very rich faceting experience delivers to the end user.
Full Entity support
Supports Custom Entity indexing through hooks. Examples such as Apachesolr Commerce,
Apachesolr User and Apachesolr Term can give you a headstart in developing your own indexing code for your entity
All of the configs for 7.x-1.x and 6.x-3.x should be exportable using your preferred way of working. If you see something that cannot be reverted of exported properly, please file a bug report.


The module comes with schema.xml, solrconfig.xml, and protwords.txt files which must be used in your Solr installation in order to get the module to work correctly.

See the documentation in the handbook as well as the included README.txt for 7.x-1.x, README.txt for 6.x-1.x or README.txt for 6.x-3.x for information on requirements and installation.

Found a bug?

Before you post a bug, maybe sure you read about how to report and solve problems. Support issues dealing with server setup and configuration may be summarily closed, since they are beyond they scope of the Drupal module.
