Learn about the SharePoint 2013 Search Topology and how it differs from 2010. In this presentation, I explain the details of all search components, how to properly configure your search topology, and your options to extend your search farm in a hybrid “cloud/on-premise” scenario. This session will explain what you need to consider to design your search, in order to handle your organization's needs. I dive into scripting a high availability search topology, keeping it healthy and manage your day-to-day search operations.

Learn about how to optimize your search for best performance and search relevancy, to support reliable search applications.

  • CPU load Driving factors QPS Query transformations Network load Driving factors Number of index partitions Size of queries and results Example: 20 index partitions @ 20 qps => 200/100 Mbit/s in/outbound Item count DPS QPS Load impact (relative) CPU Network Disk
  • CPU load Driving factors QPS and item count Guidelines per index component @ 2 GHz CPU 1M items: 5 QPS per CPU core 5M items: 2 QPS per CPU core 10M items: 1 QPS per CPU core Disk load Driving factors QPS and item count New content invalidates caches Disk size: 500GB @ 10M items per index component Item count DPS QPS Load impact (relative) CPU Network Disk
  • CPU load Driving factors Documents per second Link discovery Crawl management Network load Driving factors Downloading items from content sources Passing items on to CPC Disk load All documents are temporarily stored in data folder Item count DPS QPS Load impact (relative) CPU Network Disk
  • CPU load Driving factors Documents per second Document size and complexity Feature extraction Estimate: 5-10 DPS per CPU core Network load Driving factors Documents per second Document size Item count DPS QPS Load impact (relative) CPU Network Disk
  • CPU load Driving factors Number of items Site activity Disk load Local disk used for temporary storage Bulk load, primacy concern is load isolation Network load Same as for CPU load PLUS: Network traffic increases when distributing APC across multiple machines Item count DPS QPS Load impact (relative) CPU Network Disk
  • Low CPU and network load Load increase with more components in the search topology Item count DPS QPS Load impact (relative) CPU Network Disk

  • Conceptual Relevance Flow For all queries: Authorities: Level 1: http://employment Ranking model: {incorporate user ratings} Query: HR Employment quarterly report Search Web Part Query Processing Engine Document Collection Thesaurus: HR  Human Resources Best bets: HR Employment /HR/employment (WORDS HR, Human Resources) AND (WORDS employees, employed) AND (WORDS quarterly, quarterlies) AND (WORDS report, reports, reported) Mixed Results for: • HR Employment best bet • HR Employment quarterly report • HR Employment ContentType=reports Dynamic Reordering Rules: Quarterly Report  {prefer docs from http://reports} Query Rule: {Terms} Quarterly Report  {Terms} ContentType=“reports”
  • Sites that are important Sites with low intrinsic relevance Takes ~24hrs to propagate
  • Setting an authority affects all sites connected through hyperlinks Sites are weighted by distance to the authority
  • Tune Search Results Created at the SSA, Tenant, Site Collection or Site SSA Site Collection Site
  • Condition When Do I apply the rule? Action What to do when the rule is matched? Publishing When should the rule be active?
  •  Exact match, beginning or end  Ad-hoc or term store dictionary  Match a regex (advanced)  Is this query more likely aimed at the following source…?  Do people mostly click on result of the following type…?  Show a promoted result  Show a block of results  Replace the core results with a different query
  • Dynamically Ranking Change Part of the query Results Ranking
  • High Availability and Performance Better Search Quality Better management Friendly results and tools Session Objective and Takeaways
