PDF Viewer script

I have to use PDF Viewer in Ignition 7.9 to show electrical schema.
I want search automatically one word in pdf document with a script, and then when open the screen
containing pdf viewer controller show directly the correct page.
If is no possible do this by script could be ok also open a specific page of pdf file.

Take a look at the two ways to navigate directly to a page I show here: PDF Viewer Page Numbers Accessible?
