The Advantage of Restricting Documents to One Category

Categorization analytics in Relativity allows a single document to be assigned to more than one category, but no more than five. If a document meets the criteria for more than the X value set in the Maximum Categories Per Document field, the document will only be assigned to the X most conceptually relevant categories.

There is an advantage to leaving the value in this field at its default value of 1. When a document is only assigned to one category, it will be possible to sort documents on the Category Rank field. There will be a one to one relationship between the document object and the rank field, and it will be possible to sort in the Analytics Categorization Result list.

If the max categories per document is more than 1, there will be a multiple object relationship for the document to rank values, and sorting will not be possible.
