NEAR search results not displaying correctly?

Hello,

I’m new to DTPro and seem to have a problem with the NEAR search function. To illustrate, when I search for “red NEAR blue”, it’ll highlight ALL occurrences of red and blue in a given document instead of only those were red and blue are near each other. This makes it very difficult to locate the results I’m looking for, particularly in large PDF documents. Am I doing something wrong or is it supposed to be like that?

Thanks!

Unfortunately highlighting of occurrences does not yet apply proximity operators, in case of PDF documents due to technical limitations of Mac OS X’s PDFkit framework.
