How can I search fillable field names across multiple pdfs. Advanced search does not seem to work. I'm trying to find all pdfs that use a certain field name.

Thanks for the answers!

I don't have Pro but I'll consider getting it.

I couldn't get the batch file to run but I'll keep working on it as time permits.

This script runs from the Console Window and will search all currently open documents. It could be easily modified to work in an Action.

var aDocList = [];

var oDoc;

for(i=0;i<app.activeDocs.length;i++)

{

     oDoc = app.activeDocs;

     for(var n=0;n<oDoc.numFields;n++)

     {

         if(oDoc.getNthFieldName(n) == "SearchFieldName")

         {

              aDocList.push(oDoc.path);

              break;

          }

      }

}

The Advanced Search function only searches the value of fields, not their names.
You can use an Action (if you have Acrobat Pro) to print out a list of all files that contain a certain field-name.
