# Suggest Categories for Text

You can use the `CategorySuggestFromText` action to suggest categories from the IDOL category index that are conceptually similar to specified text. For example:

    action=CategorySuggestFromText&QueryText=Caring for passiflora incarnata

In this example, the IDOL Category component returns categories that are conceptually similar to the text `Caring for passiflora incarnata`.

It is possible to configure a spell checking engine to detect spelling mistakes in the input for this action and use the corrected terms to suggest categories. `TextParse` input is also spellchecked and categories are suggested based on the corrected terms, without changing the spelling in the document being ingested.

For configuration details refer to IDOL Server Reference.
