Мой ElasticSearch хорошо работает для поиска, но я думаю, что мой контроллер Suggest настроен неправильно. Я пытаюсь взять поле Title и использовать его для предложения.
Я использую Nest v7.5.1 и Elasticsearch. Net v7.5.1.
Модель пакета :
public class Package
{
public string Title { get; set; }
public string Summary { get; set; }
public string ResultDisplaySummary { get; set; }
public string IconUrl { get; set; }
public string URL { get; set; }
public string[] Tags { get; set; }
public string ResultType { get; set; }
public string Keywords { get; set; }
public CompletionField Suggest { get; set; }
public string PestControlledBy { get; set; }
public string PesticideControlsThesePests { get; set; }
public string PesticideInstructions { get; set; }
public string PesticideActiveIngredients { get; set; }
public string PesticidesContainingThisActiveIngredient { get; set; }
public string PesticideSafeOn { get; set; }
public string PesticideNotSafeOn { get; set; }
}
