Configuring Managed Properties in Search Service on Server

Introduction

If you want to make your custom property searchable then you need to create a managed property for that custom property.

I have added a new property "Initials" to my User Profile Synchronization Service and mapped it to a property from AD. That works and the property is properly imported into the user's profiles. I have even managed to successfully show it in search results; however I still can search for it specifically.

This managed property acts as a bridge between the search and custom properties.

Step 1
In SharePoint Search Service, select the "Search Schema" option.



Step 2
Select "New Managed Property".



Step 3
The following Managed Properties need to be created.

1. Country
   
   
   • Property Name: Country
   • Type: Text
   • Searchable: Yes
   • Queryable: Yes
   • Retrievable: Yes
   • Allow Multiple Values: No
   • Refinable: Yes-active
   • Sortable: No
   • Safe: No
   • Alias: --
   • Token Normalization: Yes
   • Complete Matching: No
   • Include content from all crawled properties: Yes

Select "Add a Mapping".





Select "All Categories" then search for "Country" then click "Ok".
The property is mapped as given in the following screen shot:



Conclusion
This tracking has an impact on the relevancy of search results. For example, a search result that is often clicked by users will automatically be displayed higher up in the search results.
