In Revit, click "Add-Ins" / "String Search" to launch the command. In the dialogue that appears, you can type in the search string in the 'Find what' text box. Click 'OK'.

The command will search for the given string on all standard and user parameters of all elements in the current view. All occurrences of the search string are listed in a data grid view in a modeless navigator dialogue.

Double click on a row in the navigator to zoom to the element. A log file of the search operation and its results are created in your temporary directory. To view the log file, right-click on the search form and select 'Display Log File’.

The string matching options and the elements and parameters to search can be modified by specifying the category, parameter name, and other options described in the Help documentation.
