#spsnh #spsnj search topology & optimization
DESCRIPTION
This presentation explains 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-prem” scenario. You will learn what you need to consider to design your search, in order to handle your organization's needs. We will 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. Together, we will review where Search lives in the farm, the crawl components of search to implement a scalable farm.TRANSCRIPT

Hybrid Search
Why Hybrid Search?Hybrid SharePoint environment
Pieces of content distributed across multiple environments
Complexity due to multiple locations
No single Enterprise Search Center for finding content
Lost user productivity and added frustration while trying to locate relevant content
BenefitsProvide integrated search results allowing for a
single place to find contentOne Enterprise Search center to reduce User
Interface complexityQuery all of your SharePoint content at the same
timeAllow O365 and On-Premises solutions to coexistProvides a solution allowing customers to move to
the cloud on their own termsReduce operation costTake advantage of newer SharePoint feature
updates in O365Hybrid search solves many problems as data is
moving from on-premises to O365

Tweaking Your results
Challenges: Intent
Where is my talk Project Plan?
Are Documents held at the same place?
I wonder if there are references from
previous projects?Different people have different intents
Query Rules help you handle intents
There is rarely a single right answer

Authorities: SSA-level configuration
Sites that are important
Sites with low intrinsic relevance
Takes ~24hrs to propagate

Query Rules
ConditionWhen Do I apply the rule?
ActionWhat to do when the rule is matched?
PublishingWhen should the rule be active?
Query Rules
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…?
Conditions Show a promoted result Show a block of results Replace the core results
with a different query

Dynamic Reordering Rules: Quarterly Report {prefer docs from http://reports}
Query Rule: {Terms} Quarterly Report {Terms} ContentType=“reports”
Create a Query Rule – Hybrid From Result Source drop-down list, select the specified result source
Under Query is performed on these sources, if you select “One of these sources”, make sure to select the result source you created
Hybrid Results
Results from SharePoint Online
Results from SharePoint Server
Session Objective and Takeaways High Availability and Performance
Better Search Quality
Better management
Friendly results and tools
