Chapter 12. Search

The success of Content Management Systems depends on their ability to locate the required content with the least amount of clicks. The way you choose the content name, the way you categorize the content, the location where you place the content, and the meta-data property values that you provide will all help you to locate the content more easily. You will realize the benefits of having a powerful search engine when you have a large number of files in your Content Management System. In this chapter, you will examine the advanced search features of Alfresco, and extend the capabilities of search.

Overview

Unlike many commercial Content Management Systems, Alfresco includes a free and very powerful search engine called Lucene as part of its installation. Therefore, you don't have to buy and install a third-party search engine. Moreover, you don't have to deal with integration issues and upgrades.

By using Alfresco, you will be able to search both content and properties. You can perform a full-text search on any word in the content, regardless of the format. You can search for content in a particular space. You can also search for content belonging to certain categories or of a specific type. You can search for content created or modified between certain dates, created by a specific person, and so on. You can extend the search capabilities to search for custom content types and custom property values.

By default, all content in Alfresco is full-text searchable. Any content that has been uploaded to Alfresco, such as the following types, will be internally converted to text, indexed and made searchable:

  • Microsoft Office documents, MS Word, Excel, PowerPoint
  • Open Office documents
  • XML/HTML
  • PDF
  • Emails
  • Content in foreign languages
