Sharepoint 2013 Auto Create Managed Property not work

Question

Hi i developed a site column, custom content type and a list definition. I set the value for this column and started crawling but i don't find these properties in search schema. If i add this column manually in a library and start crawling, these properties are showed. What 's the difference?

Answer 1

I think it should work as you described - the following steps are needed, maybe you can try again:

To be picked up, the new items must be crawled. If you’re not using Continuous crawling, this will be limited to when your incremental crawls run.

The column must be a site column!

To be picked up, crawled properties MUST have a value.

To be applied to items already existing in the index, a full crawl will be required still.

Or Technet: http://technet.microsoft.com/en-us/library/jj613136.aspx

Btw, I would not recommend you the automatically approach, you loose a lot IMHO. The managed property benefits a lot when you merge several crawled properties into one managed property.

Answer 2

The difference between setting the column as index-able at the list level will mean that all other lists that have this column will not be indexed.

To expand on Max's list I also recommend:

• Index reset

I have seen scenarios where following the steps Max outlined ends in the crawled property still not being created. I recommend manually creating the properties.

You can create the managed property and crawled property in the search administration page or via powershell script using the following commands:

$crawledproperty = New-SPEnterpriseSearchMetadataCrawledProperty -SearchApplication [search app] -Category [Category] -PropSet [Property set] -Name [Name] -IsNameEnum $false -VariantType [crawled property template varient type]

$managedproperty = New-SPEnterpriseSearchMetadataManagedProperty -Name [ManagedPropertyName] -SearchApplication [searchapp] -Type [property type] -FullTextQueriable [$true or $false] -Queryable $true -Retrievable $true -EnabledForScoping $true -NameNormalized $false -Safe $true -NoWordBreaker [$true or $false] -Description [Description] -Refinable [$true or $false] -sortable [$true or $false] -HasMultipleValues [$true or $false]
