The advanced search syntax can be used to search for documents that contain images or those without. The syntax for this type of search is shown below.
The term Img specifies whether a document should have images before it can be considered a valid search result. If the Img value is Y, all documents that have images will be considered valid search results. If the Img value is N, all documents that do not have images will be considered valid search results.
Note: For the purposes of this type of search, a document is considered to not have images when you cannot view images from the Document window.
The first sample search will find all documents that have images, while the second one will only find documents that do not have images.
