When you execute a search template that was created by Search Designer, your search values, such as the document title or author, must correlate to the appropriate item IDs within the search template itself.
The first search property within the search template often has an item ID of 1, the second property has an item ID of 2, and so on. However, this is not always true, especially when with search templates that have had many changes.
To determine the item IDs for the search properties that are defined in a search template, examine the XML content of the search template.
