Build Categories
You can use the CategoryBuild action to build a category. You must build a category after you create it and train it, as well as every time you retrain it. Building a category identifies the concepts of the category’s training and indexes the category into the IDOL server category index. For example:
In this example, IDOL server builds the category with the ID 32349987602210557106.
NOTE If you train or retrain a category using the CategorySetTraining action with BuildNow set to true, you do not have to execute a CategoryBuild action, because the category was built immediately after it was trained.
