Changes in Search in SharePoint 2013

 

 

    SharePoint 2013   SharePoint 2010
Code Base   The Search engine is a combination of SharePoint search and FAST search engines (single code base) hence advanced capabilities that were earlier available for FAST Search deployments will now be available to SharePoint deployments. There are two product lines – SharePoint Search and FAST Search (code bases are different).  Examples of capabilities specific to FAST Search for SharePoint are:

  • Content-processing pipeline
  • Metadata extraction
  • Structured data search
  • Deep refinement
  • Visual search
  • Advanced linguistics
  • Visual best bets
  • Extreme scale and performance
Logical Architecture   Addition of Content Processing, and Analytics Components. The components are

  • Crawler
  • Content Processor
  • Analytics Processor
  • Indexer
  • Query Processor

Search Administrator component runs number of system processes required for search, is responsible for search provisioning and topology changes and coordinates search components – Content Processing, Query Processing, Analytics, and Indexing.

Crawler component was responsible for content/document processing. The components are

  • Crawler
  • Indexer
  • Query Processor/Server

Administration is done through Central Administration site

Crawling   Anonymous crawling of http sites is possible.
Continuous crawl for SharePoint content sources is available. Because of changes in how the index is created and stored, a document can appear in the index within seconds of going through the content processing component
Waiting period is long for index to merge and show results
Result Sources   Specify a location to get search results from and specify a protocol for getting those results Functionality available by Federated Search and Scopes
Analysis Engine   Run time analysis engine for a variety of jobs including ranking algorithms and recommendations.
Search Analytics

  • Link and Anchor text analysis
  • Click Distance
  • Search Clicks
  • Deep Links
  • Social Tags
  • Social Distance
  • Search Reports

Usage Analytics

  • Recommendations
  • Usage Counts
  • Activity Ranking
Web Analytics in Central Administration provides usability reports and administration reports that mentions latency, crawl throughout and so on
End-User Experience   Direct access to the most granular information inside of sites and documents, and then enables users to act on the results without having to leave the results page.
Every search box in every team site offers full access to enterprise-wide search, people search, and other specialized search experiences in addition to the traditional scoped site search
A user enters a set of search terms on a search center homepage that are treated as keywords, and the results are a single ranked list of links with three-line summaries and a little metadata.
Hover Panel   New in SharePoint 2013.
Shows visual previews of sites, documents, and conversations. New set of actions that users can perform right on the search result. For example, following a document, leaping right into Edit mode, or sharing or opening the library the document is stored in to see what other content is available
Not Applicable
UI Framework   The UI framework that supports all these new features is re-designed. It is based on a set of nested layout templates that are defined in JavaScript and HTML for much easier extensibility SharePoint Server 2010 includes many search-related web parts for power users to create customized search experiences, including Best Bets, refinement panel extensions, featured content, and predefined queries
Expertise Search   Document Authors are identified as experts based on the content mentioned in the document (Word, PowerPoint, PDF) My Site profiles identifies expert in an area
People Search   People Search is integrated with core results. People search can be targeted by name, location, phone number and other properties People Search is independent of document search
Managed Properties   Organization specific dictionaries with custom entities can be mapped to managed properties
Results Rendering Approach   Asynchronous client-side approach Server based rendering approach

 

Query Rules   Query Rules are a new feature in SharePoint 13 that help act upon the “intent” of a query –
Query Rules are composed of three top level elements:
Query Conditions (i.e. matching rules), Query Actions (i.e. what do you do when you find a match),
Publishing Options (i.e. when should this rule be active).
Query Rules allows to have search requests from a user trigger multiple queries and multiple result sets
Simple queries – one query has one set of results.
Document Parsing   New parsing features

  • Automatic file format detection
  • Deep link extraction for Word and PowerPoint formats
  • Visual metadata extraction: titles, authors and dates
  • High-performance format handlers for HTML, DOCX, PPTX, TXT, Image, XML and PDF formats
  • New Montage, Visio and OneNote filters
  • The IFilter API continues to be supported as a means of extending the supported set of file formats
Document detection relies on file extensions
