With that, the operation IDs would be renamed from things like `items-get_items` to just `get_items`, that way the client generator can generate simpler method names.

### Generate a TypeScript Client with the Preprocessed OpenAPI { #generate-a-typescript-client-with-the-preprocessed-openapi }

SuggestResponse response = suggester.suggest()
    .setQuery("sea")                    // user input
    .setSize(10)                        // max suggestions

response.getItems().forEach(item -> {
    System.out.println("Suggestion: " + item.getText()[0]);
    System.out.println("Score: " + item.getScore());
});

После этого ID операций будут переименованы с чего‑то вроде `items-get_items` просто в `get_items`, и генератор клиента сможет создавать более простые имена методов.

```Javascript

Con eso, los operation IDs serían renombrados de cosas como `items-get_items` a solo `get_items`, de esa manera el generador del cliente puede generar nombres de métodos más simples.

Damit würden die Operation-IDs von Dingen wie `items-get_items` in `get_items` umbenannt, sodass der Client-Generator einfachere Methodennamen generieren kann.

Com isso, os IDs de operação seriam renomeados de coisas como `items-get_items` para apenas `get_items`, dessa forma o gerador de clientes pode gerar nomes de métodos mais simples.
