- 4. What’s Solr? • Apache Solr is an open source enterprise full-text search server • Created by Yonik Seeley for CNET • Contributed to Apache Jan 2006 • Version 1.4 released Nov 2009 • Uses Apache Lucene Java search library at its core for full-text indexing and search • Runs within a Servlet container such as Apache Tomcat • It supports any programming language since it has REST-like HTTP/XML and JSON APIs © Copyright 2012 Ixxus Ltd. Commercial in Confidence 4
- 5. What’s Solr continued? • Written in Java and provides plug-in interfaces for building extensions to the search server, such as: • Faceted searches and navigation • "Did you mean" spell checking on queries • Query completion • Finding documents that are "More like this" • Results highlighting • Geospatial search for filtering and sorting by distance © Copyright 2012 Ixxus Ltd. Commercial in Confidence 5
- 6. What’s Solr continued? • Conceptually, Solr can be broken down into four main areas: • Schema (schema.xml) • Field types and fields (including dynamic fields) • Configuration (solrconfig.xml) • Lucene index parameters • Request handler mappings • Cache settings • Plug-ins • Indexing • Searching © Copyright 2012 Ixxus Ltd. Commercial in Confidence 6
- 7. What’s Solr continued? • Security? • Relies on server or container security • Totally open by default, you need to secure it! • No standard document level security model © Copyright 2012 Ixxus Ltd. Commercial in Confidence 7
- 8. What’s a Solr Core? • A Solr core holds one Lucene index and the supporting Solr configuration for that index • Sometimes the word "core" is used synonymously with "index“ © Copyright 2012 Ixxus Ltd. Commercial in Confidence 8
- 9. How is Solr integrated with Alfresco • Alfresco uses a patched Apache Solr 1.4 version • Custom Schema • 2 cores: © Copyright 2012 Ixxus Ltd. Commercial in Confidence 9
- 10. Why is Alfresco using Solr? • The following are some of the reasons why Alfresco decided to move from an embedded Lucene search engine to the stand- alone Solr search server: • Scale content search independently • Make clustering easier • Improve performance • Support cross-locale ordering © Copyright 2012 Ixxus Ltd. Commercial in Confidence 10
- 11. What Alfresco Repo content is searchable? • What content in the Alfresco repository is searchable via Solr? • All content in the Workspace store (the main store used for most of the live content) • All content in the Archive store (content that has been soft deleted) • What’s not searchable? • Content in other stores such as AVM (deprecated and being phased out) is not supported • Multi-tenant searches are not supported in version 4.0.0 (supposed to be supported in later versions 4.c) • Records Management (RM 2.0 will support Solr) © Copyright 2012 Ixxus Ltd. Commercial in Confidence 11
- 12. When not to use Solr? • If you are not running in Tomcat • Want to use Records Management Module • Require in-transaction indexing © Copyright 2012 Ixxus Ltd. Commercial in Confidence 12
