  • The purpose of the search capacity test is to validate the documented and undocumented soft boundaries in Microsoft SharePoint Server 2013, with focus on maximum number of documents in search partitionmaximum number of documents in a crawl databasearchitecture for crawling a large number of file sharesgetting an initial picture of search and crawl performance Crawled 30 million documents from file shares via symbolic links on crawler server. Tested 20,000 searches per day and used top 300 used searchqueries from searchstatistics.4 server farm with 2 indexpartitions, 2 crawl component and 1 crawl database.
  • Slide shows actualnumberswith 31 million itemsindexed
  • Display templates control which managed properties are shown in the search results, and how they appear in the Web Part. Each display template is made of two files: an HTML version of the display template that you can edit in your HTML editor, and a .js file that SharePoint uses.Control templates determine the overall structure of how the results are presented. Includes lists, lists with paging, and slide shows.Item templates determine how each result in the set is displayed. Includes images, text, video, and other items.Group templates is special for search results and is used for html surrounding grouped itemsHover templates is used for presenting more information on a search result hit. A item template and a hover template have a connection

  • We have learned that…You will need Performance will get you• Funding!• Time • Add more CPU• Documentation • Add more Memory• Network • Optimize Disk IO• To automate • Balance load vicely • Tune Distributed cache • Know your Anti virus
  • Capacity Test Findings• Crawl rate decline 1% per million items indexed• Query latency increase exponentially from 12 million items indexed per partition• Database latency insignificant during crawling• Successfully crawled file shares via symbolic directory links• Disk space usage significant lower than expected

  • USER EXPERIENCE&SEARCH CUSTOMIZATIONS
  • Display templates• Content search webpart – Control, item• Refinement webpart – Control, item• Search result webpart – Control, group, item, hover
  • FRONT Search• Advanced query and result processing• Highly customizable business logic represented through reusable tasks and flows• Lightweight development environment• Lightweight deployment• Fully integrated with SharePoint result presentation and display templates• Fully integrated with SharePoint security
  • FRONT Search in SP2013• Front webpart – Handles communication between Front and UI• Front app – Handles claims security• Front webservice – Flow engine
  • FRONT Search in SP2013• Javascript events – QueryIssuingEvent – ResultReadyEvent• Search Rest API – Query, postquery and suggestions – Json and XML result – Windows security / claims – http://host/site/_api/search
  • FRONT Search <=> Query rulesFRONT Search Query rules• Conditions • Conditions – Analyze query – Analyze request – Six types – Full flexibility • Actions• Tasks (Actions) – Change query model – Add promoted result – Perform parallel queries – Add blocked result – Full flexibility – Change query• Publishing – Special conditions case • Publishing• Result processing – When is the rule active – Analyze result from a query – Perform new queries based on result – Change order/grouping/content of result
  • FRONT Search <=> Result sourcesFRONT Search Result sources• Source system • Source system – SP 2013 – Local SP 2013 index – SP 2010 – Remote SP 2013 index – FAST ESP – OpenSearch – Lucene/Solr • Query transformation – … – Subset of content• Query transformation – Full control of query model

  • How do you index millions of documentsin thousands of file shares in hundreds of locations? Bonus! Support governance and operations
  • Challenges• Max 50 content sources per service application• Max 100 start addresses per content source• Max 20 concurrent crawls per service application• Limit bandwidth usage for specific server locations• Limit crawler impact within local business hours• Grant read access to crawler per file share• Avoid token bloat issues with more than 1000 groups per account• Manage indexing and crawling of each file
  • A Proven Approach• Symbolic links in smart folder • Host aliases for crawler impact structure • Custom timer job that synchs custom lists from custom app impactfilessourceimpactaccountsymlink • Custom timer job that creates/removes symbolic• Content Sources per region links with smart start addresses • Custom list: Locations file://impact/files/source/impact – Map server prefix to content source• Content Enrichment to fix file – Map location to schedule paths in results and impact• Custom application for • Custom List: File shares managing file shares and – Map share to crawl account granting access to crawler – Map UNC to symlink – Map share specific
  • Example SolutionFiles in Norway Crawler Impact Rules• Incremental Crawl every 6 hours • Server name: default• Start address: file://default/files/norway/default • Server name: reduced wait 60 secsFiles in India Crawl Rules• Incremental Crawl every night at 21:00 IST • file://*/user1/* account=user1• Start address: file://reduced/files/india/reduced • file://*/user2/* account=user2Custom list: File Shares Folders• UNC Path: osl-file01share1hr • files/norway/default/user1/symlink1• Crawl Account: user2 • files/norway/default/user1/symlink2• Symlink: files/norway/default/user2/symlink3 • files/norway/default/user2/symlink3 • files/india/reduced/user1/symlink4Custom list: Locations • files/india/reduced/user1/symlink5• Server Prefix: osl • files/india/reduced/user2/symlink6• Content Source: norway• Crawler Impact: default
  • Discover associations in your indexed data using custom entity extractors Explore how your • Examples indexed data is – Organizationassociated with terms – Projects often used by your – Customers business – Products
  • Add metadata or clean up your indexed data using custom content enrichment• Based on where the • Remove company items are located, add name from title for all info about web pages – Department • Normalize names – information owner, • Normalize phone – Security classification numbers• Lookup name based • Fix search result link on user account

  • How fast can you findwhat you are searching for? - Relevancy - Recall – Precision -• What should be • How to a weight a indexed? managed• What should be property? searchable? • How to change• What should be ranking model? displayed? • How to tune ranking?
  • Managed Property Weighting These are not ordered by importance!
  • Change Ranking Model• The default ranking model in SP 2013 did not fit us! – Power Points always won We replaced the SP – Complete matches in site 2013 ranking model titles and document titles with the SP 2010 were outranked by number ranking model of partial matches in body – Community sites were weighted lower than discussions and posts
  • Tune Ranking ModelMicrosoft will soonrelease a tool for tuningranking models!1. Select ranking model to tune2. Select result source to search3. Add judgement sets4. Add queries to judgement sets5. Run queries and evaluate results6. Add and tune features7. Save and publish model
