New / Updates Ranking Model functions:
Custom ranking models are managed through PowerShell using XML files as it was in SharePoint 2010. Ranking Model for a specific query can be selected at query time by setting the RankingModelId of the query otherwise the default is used.
The PowerShell cmdlet is: New-SPEnterpriseSearchRankingModel
For more details about the underlying XML schema have a look here.
This example shows all Ranking Models in my demo system. You can see which is the default:
You can use the configured Ranking Models, for example, in the Query Builder (see details below in the Query Builder Section):
Query Spelling Correction:
This function is hosted in the Termstore. We can now easily configure “Exclusion” and “Inclusion” Terms. Another big benefit is that Terms configured in the “Inclusion” Termset can also be used for “Did you mean” functionality.
The example shown in the picture would result in searching for ”EI” which didn’t get any results so the system will suggest “Did you mean ExpertsInside”
Query Rules are new in SharePoint 2013. It is a feature that gives us the option to tailor results in a very flexible way. Query Rules are set on Site Collection Level.
A Query Rule has 3 main parts:
- Query Conditions
- The conditions defined when and in which context the rule became active:
- Query Action
- In this section we can defined what happened if the rules matched. This is just a little bit similar to what we know as “Best Bets” or “Visual Best Bets” from SharePoint 2010, but much more powerful.
- Publishing Options
- These settings control when the rule can fire
Query Client Types:
Query Client Types are also new in SharePoint 2013 Search. At this time there aren't many details are available on this new function. The idea behind the function is using the client the query is sent from to do specific throttling etc: “Applications are prioritized by tiers. Top tier has the highest priority. When resource limit is reached, query throttling becomes ON, and search system will process the queries from top tier to bottom tier.”
Query Builder is a tool in SharePoint 2013 Search which we can find in different places. For example the Query Builder is available in the “Result Sources” section (Result Sources are in the next Part IV – Admin Stuff) and also in the “Query Rule” section etc. Query Builder is available when we have the option to manipulate search query or refine it. The Query Builder has 3 tabs:
