The Similar Text request returns information about the index items within its results. This information can include the other item sets of which the items belong too (since they can be multiply linked). The number and type of related sets to return per index item is controlled by the following attributes:
<similardocs maxRelatedSets="max" relatedSets="path,path,..."
The max value is the maximum number of related sets to return. A value of 0 means no related item set information is returned in the response. The default is 1000. The path values are item set paths (for example, /Topics/Product) which act as constraints on what type of related sets to return. Only related sets that are descendents of one of the path values are returned. The default value is an empty string, which means that the related sets are unconstrained.
