# 如何帮助用户消除相似结果之间的歧义
<a name="suggest-disambiguate-results"></a>

通过建议 API，您可以针对地点或结果类别创建查询。结果按照匹配可能性从高到低进行排序。每个结果都会提供相关信息，可帮助您快速确定正确的匹配项，尤其是在“标题”和“标签”字段方面。

## 潜在使用案例
<a name="suggest-disambiguate-results-potential-use"></a>
+ **显示结果选项：**您可以选择最符合自己需求的选项。

## 示例
<a name="suggest-disambiguate-results-examples"></a>

“标题”字段的信息通常足以让您了解结果何时达到预期效果。对于标题未提供足够信息的情况，“标签”字段用于为结果添加地址信息上下文。“标签”字段可作为额外信息提供，当为您呈现结果时，正文中不会强调该字段。下面的示例中提供了两个相似的结果，酒店的地址可帮助您选择更适合您需求的结果。此外，还提供了位置，以便在地图上呈现结果，作为您在结果之间进行选择的另一种方式。
