## Example { #example }

Here's an example *path operation* with parameters using some of the above types.

{* ../../docs_src/extra_data_types/tutorial001_an_py310.py hl[1,3,12:16] *}

Note that the parameters inside the function have their natural data type, and you can, for example, perform normal date manipulations, like:

        }
        return name;
    }

    /**
     * Executes a search operation with the specified parameters.
     * This method must be implemented by concrete searcher classes.
     *
     * @param query the search query string
     * @param params the search request parameters including pagination, filters, etc.
     * @param userBean the optional user bean for access control and personalization

///

/// tip

Notice how each model's attribute with a type, default value and `Field` has the same structure as a *path operation function's* parameter, with `Field` instead of `Path`, `Query` and `Body`.
