According to google you only get ten tokens per attribute for filtering. I have not been able to get around it.
To be more specific about my original problem, I was storing multiple doctor-page paths in a clinic-page that were getting tokenized on every /
. I solved my problem by searching for the clinic-page in a doctor-page label, rather than reading the doctor-pages from my clinic-page search result. I used repeated attributes to be able to search, like
//inside clinic-page
<Attribute name="doctor">path/to/doc1</Attribute>
<Attribute name="doctor">path/to/doc2</Attribute>
...
But that does not allow you to read every doctor-page from a clinic-page result. This happened to work in my case. Google definitely restricts its tokens to ten per attribute.
