I am trying to create a custom filter that would search for a list of caches with certain attributes. However, it appears that I am limited to the number of statements that I can add to the filter. I was able to add 6 statements to a positive filter but only four negative statements in a different filter. I had to break out and create another filter for the remaining negative attributes, but I could only add three statements in that filter. Is this a glitch or just a limitation?
