What must be included when using a suggestion function to provide user data?

To utilize a suggestion function effectively, it is essential to include a single Text parameter. This parameter serves as a critical input that guides the function in generating relevant suggestions based on the user's query or input. The Text parameter typically represents the user's current input or search term, allowing the suggestion function to analyze it and return contextually appropriate results.

For instance, when a user starts typing in a search field, the Text parameter captures the partial input. The suggestion function then processes this input to identify matching data points, thereby enhancing the user experience by providing instantaneous and relevant options. In the context of Appian, this method is often employed to streamline data retrieval and improve the interface's responsiveness to user actions.

Other choices do not fulfill this requirement as effectively as the Text parameter. Numeric parameters might be used in different function contexts, but they do not align with user input for suggestions. A Boolean flag may indicate conditions or options but does not directly represent user data for suggestion purposes. A list of items is not a parameter that can actively receive user input, as it serves as a collection of potential suggestions instead of the criteria to generate them. Therefore, the inclusion of a single Text parameter is what enables the suggestion function to operate correctly and meet user needs.
