Adaptive scopes Retention Policies Data Lifecycle Purview

Microsoft recently implemented “Adaptive” retention policies. At step 2 of “Create retention policy” you’ll be asked “Choose the type of retention policy to create”: “A policy can be adaptive or static. Advantage of an adaptive policy will automatically update where it’s applied based on attributes or properties you’ll define. A static policy is applied to content in a fixed set of locations and must be manually updated if those locations change.”

And if you selected “Adaptive” – on the next step you will need to provide the adaptive scope (so at this moment you should already have created your adaptive scopes):

So, let us create your adaptive scopes.
What type of scope do you want to create? SharePoint sites…

And then you’ll have nothing more then set of conditions:

where you can use objects: “Site Url”, “Site Name” and “Refinable String 0″..”Refinable String 99”. Conditions would be “is equal to”, “is not equal to”, “starts with” and “not starts with”. Or you can select “Advanced query builder” and enter KQL query.

Advanced query builder

Advanced query builder allows us to use more site properties then “Site Url”, “Site Name” and “Refinable Strings” and more conditions than “is (not) equal to” and “(not) starts with”.

E.g. we can use “Title”, “Created”, “Modified” site properties and “=”,”:”,”<“, “>”, “<=”, “>=” conditions.

Working queries examples:

created>12/31/2021 AND modified>=7/31/2022

Not working queries examples:

RefinableString11 = Birds # (do not use spaces in advanced query)

Query against custom site property (aka property bag value)

You can create custom site property and assign value to the property with
Set-PnPAdaptiveScopeProperty or Set-PnPPropertyBagValue.
Property must be with “Indexed” parameter. Once the property is set up, m365 search crawls site and creates crawled property. Then you map crawled property to some pre-created refinable string managed property. You can assign alias to this managed property.

In my test scenario I used RefinableString09 with alias SiteCustomSubject.

Site property valueQueryresult
BirdingRefinableString09:Birddoes not work
BirdingSiteCustomSubject:Birddoes not work
BirdingSiteCustomSubject:Bird*does not work
BirdingSiteCustomSubject:Birdingdoes not work

Query against multi-value property.

Site property valueQueryresult
TestA TestBRefinableString09:TestAworks
TestA TestBRefinableString09 = ‘TestA TestB’does not work
TestA TestB??? RefinableString09=’Test10 Test5′does not work
TestA TestBRefinableString09:TestB ?
TestA,TestBRefinableString09=Test*does not work
TestA,TestBRefinableString09:Testdoes not work
TestA,TestB(basic) RefinableString09 starts with testworks

What is the takeaway from this for SharePoint administrators? We would be asked to configure SharePoint the way compliance/retention people can use Refinable Strings.
