- 3. WHAT HAPPENED TO FAST? FAST was a true Enterprise Search platform, so…
- 4. The evolution of FAST FDS ESP FSIS FSIA FS4SP Search in SP2013 Search in SP2010 Secret sauce (incl. Mars)
- 5. End of an era, birth of a New age • FAST now “fully integrated” into SP2013 – True, but there’s more! • No longer a “FAST license” – SP2013 contains everything – Enterprise version 1997 – 2013
- 6. Empowering the whole SharePoint experience Better, more powerful extensibility Major user experience overhaul Main themes of the new Search • User Experience is finally a key component Vastly improved search core Finally a single search architecture
- 7. User Experience is finally key • Revamped user/admin interface • Hover panels, previews • Query rules, result blocks • Result types, display templates • “You’ve seen this result before” • Query Builder • Content Search web part • Etc.
- 8. For the first time, Search isn’t defined by the nuts and bolts, but from the User Experience and high-level tools around it.
- 11. Build and extend • With the new Content Search Web part (CSWP) • With the new REST APIs
- 12. NEW SEARCH ARCHITECTURE Examining SharePoint 2013’s
- 13. Search architecture Public API Unit of scale/role boundary Extensibility Points Crawl Admin Link Analytics Reporting
- 14. The search components • A “node” is an instance of a component • Scale by adding nodes
- 15. REST service architecture • Directly interact with SharePoint artifacts by using any technology supporting REST • Also: – CSOM JavaScript, Silverlight – SSOM Managed code
- 16. The new Search Service Application
- 17. Keeping it all together Services Processes Process name Description hostcontrollerservice.exe Process controller. Monitors and restarts children. noderunner.exe A search component (except the crawl component) mssearch.exe The crawl component.
- 18. Crawl component • Changes from SP2010 – Improved performance – Continuous crawl • Improves freshness – Crawl Log • More details • Document removal – Crawl Health Report • Huge improvement!Crawl mssearch.exe
- 19. Continuous crawls • Not event-driven indexing • Starts crawl regardless of prior crawl session • Large change sets no longer bad for freshness • Only available for SharePoint content types – Possible to crawl SP 2010 and 2007 time Continuous Full and incremental Default 15 min
- 20. Crawl health reports Rate Latency Freshness CPU and memory load Content Processing activity Etc. Crawl rate per type Crawl load
- 21. Content processing component • Schema mapping – Crawled Managed properties • Entity extraction – Companies and custom • Advanced Filter Pack is gone – PDFs are out of the box • Extensible through web service • Internally: processing flows – Replaces Python pipeline Link
- 23. Index component • Propriety disk-based index • Discrete portions called partitions • 1 partition per 10M docs • Each partition contains 1+ replicas for fault-tolerance and query volume • 1 replica, 1 server • All servers perform indexing (partially in-memory)
- 24. Example: Partitions and replicas Same content Different content
- 25. Query processing component • Prepares the queries – Query rules – Result sources – Linguistics/dictionaries – Etc. • Manipulates the results – Display templates – Late security trimming – Etc. • Internally: processing flows – No custom processing as in Content Processing – Still MAJOR improvement
- 26. Query rules • For a certain term trigger certain action: – Add/change query terms – Use alternate sorting/relevance – Hybrid search (or other federated results) – Etc. • Replaces search keywords in SP2010 • Configure at farm, site collection or site-level
- 27. Query builder • Easily builds KQL – CSWP, result sources, query rules, etc.
- 28. Query client types • Adjust throttling per client type
- 29. Query health reports Trend Overall Latency in main flow Latency in each subflow Index times Etc. Latency per processing node in SharePoint flow
- 30. Analytics processing component • Analyzes crawled items and search usage • Updates index without re-indexing documents • Result: relevance becomes self-learning – Also: search reports and recommendations Link Analytics Reporting
- 31. Search reports • Self-learning relevance aside, never underestimate manual effort! – Query rules, synonyms, boosts, etc. • Automatic reports: – Number of queries – Top queries – Abandoned queries – No-result queries – Query rule usage
- 32. Search administration component • Provisions other search components • Talks to Admin database on behalf of: Crawl, Content and Query processing components • In previous FAST products, it was hard to make the admin component redundant – Not the case in SP2013! – Scale appropriately Admin
- 33. Hardware properties • Highlights – In-memory technology – VMs now supported for production – SANs less problematic Component CPU Memory Disk I/O Network Crawl Medium Medium Medium High Content processing High High Medium Index High High High Medium Query processing Low Medium Medium Analytics processing Medium Medium Medium High Search administration Low Low Low Low
