I am trying to search document in Appian Documents Tab. I am getting the documen

Use the document() function in an expression rule. Since the rule input will be a document, testing the expression rule lets you select the document to pass.

The document function allows you to retrieve useful information about the document: forum.appian.com/.../Scripting_Functions.html including the folderId so that you can do /suite/folder/ABC to access its parent folder.

Another quick way if you do not have the document Id but only the document name would be to create a Constant of type document, search for the document by name in the value section, once selected you can click on the value part and see the parent structure.

Thanks Eduardo and Pritam, I was able to find the folder
