+`skipped_docs_count`:::
+(integer)
+The number of documents that are skipped during the analysis because they 
+contained values that are not supported by the analysis. For example, 
+{oldetection} does not support missing fields so it skips documents with missing 
+fields. Likewise, all types of analysis skip documents that contain arrays with 
+more than one element.

+`test_docs_count`:::
+(integer)
+The number of documents that are not used for training the model and can be used 
+for testing.
