# Create Named Taxonomies

You can take advantage of the hierarchical nature of IDOL categorization to manually create and store named taxonomies in the IDOL Category component. You can then use those taxonomies to investigate searches or suggestions.

If you set up a hierarchy of categories using the `CategoryCreate` or `CategoryImportFromXML` actions, you can then run `CategorySetDetails` for the topmost category with `TaxonomyRoot` set to `True`. That category becomes the root of the new taxonomy and its name is the new taxonomy name.

You can also generate a named taxonomy automatically by running the `TaxonomyGenerate` action and setting `TaxonomyRoot` to `True`.

You can subsequently use the taxonomy name as a parameter in actions such as `CategoryFind` and `CategorySuggestFromDocument`, to restrict the scope of the action results.
