SharePoint 2013 Search components include the crawl component, content processing component, index core, query processing component, and analytics service. The search workflow involves crawling content from various sources, processing content for indexing, storing indexed content in the index core, handling search queries through the query processing component, and utilizing analytics. Common issues involve search components entering failed or degraded states, new content not appearing in search results due to crawl or indexing errors, and errors when opening crawl logs. Restarting services, servers, and running diagnostic scripts can help resolve many search issues.

- 24. Case 1: Search component in „failed state“ Suggested solution: • Restart server with component in failed state
- 25. Case 2: New elements are not shown in search results • Open Central administration Service applications Search_SA Crawl log Local SharePoint sitescrawl history Open first crawl log.
- 26. Case 2a: Search components OK no new elements are visible in search results • Error in crawl logs: »The crawler could not communicate with the server. Check that the server is available and that the firewall access is configured correctly. If the repository was temporarily unavailable, an incremental crawl will fix this error« • Suggested solution: • Restart server or IIS on crawl target server
- 27. Case 2b: Search components OK no new elements are visible in search results • Error in crawl logs: »The item could not be indexed successfully because the item failed in the indexing subsystem. ( The item could not be indexed successfully because the item failed in the indexing subsystem.« • Suggested solution: • Primary index component – restart service or server • Get-SPSearchTopologyState script extended to check the synchronization timer job • https://gallery.technet.microsoft.com/s criptcenter/Get- SPSearchTopologyState-b7452c6a
- 28. Case 3: Opening crawl logs throws an error Open Central administration Service applications Search_SA Crawl log Local SharePoint sitescrawl history : • »Retrieving the COM class factory for component with CLSID {0FF1CE15-0005-0000-0000- 000000000000} failed due to the following error: 800703fa Illegal operation attempted on a registry key that has been marked for deletion. (Exception from HRESULT: 0x800703FA).« • Suggested solution • Primary admin component • Restart primary admin component
- 29. Degraded state: • After server restart • After service restart • Index component in degraded state for too long Case 4: Index component in »degraded state« • Suggested solution: • Run Get-SPEnterpriseSearchStatus -Text - SearchApplication [search sa name] • Run Get-SpEnterpriseSearchStatusExtended • Usually all will show degraded state • Script Builds SP Search 2013 Index health reports for monitoring and troubleshooting https://gallery.technet.microsoft.com/scriptcenter/Build s-SP-Search-2013-10d72a25 • Look for: • Index component [I.2.0] left behind • Not seeding!!! • Restart search host controller service • Run script again • Wait for sync to complete
- 30. Search for Power User
- 31. Content Sources • Content Sources are the core to search • Without content, what is the point of search? • Content can come from anywhere • Out of the box support includes • SharePoint Sites • Web Sites • File Shares • Exchange Public Folders • Line of Business Data • Custom Repository • External content with custom interfaces can be searched! • Utilize the BCS connectors to custom code a connector to a source
- 32. Types of Crawls • Full • Full crawls will re-index everything in a content source • Content, Columns, security ACLs • Incremental • Only things that have changed (Added, modified, deleted) • Continuous • Will continually crawl content that has changed • Does NOT crawl “instantaneously” • Runs at 15 minute intervals • If not complete, will start new crawl thread
- 33. Crawl and Search Security • Crawl Security • By default, a single account is used to crawl all content • Giving read access to all your content in the enterprise is frowned upon • Consider breaking up the Read account across the different content sources to reduce exposure to hackers • BCS Connectors can be used to get security ACLS from custom sources • Search Security • Search results are security trimmed • Only content a users can gain access to will show in the search results • Means that target must contain ACLs that search can index • Custom repositories must be built to map any internal authentication scheme to Active Directory accounts
- 34. Columns, crawled and managed properties Columns: •CreatedBy •ModifiedBy Crawled properties •ows_Created_x0020_By •ows_Modified_x0020_By Managed property • Author Crawl property naming convention is: ows_q_<Type>_<ColumnName> ows_r_<Type>_<ColumnName> ows_taxId_<Type>_<ColumnName> Managed property naming convention is: <ColumnName>OWS<Type> owstaxId<ColumnName>
- 35. Display templates • HTML files • Converted to js files • Two types • Search results web parts • Content by search web parts Item <property name="ItemTemplateId" Item Item
