SP2013 - How to determine the id of your Result Source for setting the SourceId query parameter ?

Hi Search Enthusiasts !

One question I had the other day was how to determine the id of a Result Source so it could be set in the SourceId query parameter.

https://msdn.microsoft.com/en-us/library/office/microsoft.office.server.search.query.query.sourceid.aspx

Specifies the identifier (ID) of the result source to be used to run the query.

There are few ways but the easiest for me is to go the CA / SSA / Manage Result Sources

 

* Click the Result Source you would like the id from (click like for editing it).

* Copy the browser URL

* Paste it there to decode it https://meyerweb.com/eric/tools/dencoder/

* Note the SourceId parameter value and use it for querying.

Et Voila !
