忽略词序的 Azure 认知搜索建议

Question

假设在我的索引中我有这个值：

Clint Eastwood
Jamie Lee Curtis

我有这个代码简码

public void Search(string indexName, string suggester, string name)
{
    var searchClient = new SearchClient(new Uri(searchServiceEndPoint), indexName , new AzureKeyCredential(adminApiKey));
    
    var so = new SuggestOptions();
    var sugg = searchClient.Suggest<Request>(name, suggester, so);
}

进行以下搜索我得到了这个结果

Working examples:

name = clin
Suggetsion is Clint Eastwood

name = east
Suggestion is Clint Eastwood

name = clint eas
Suggestion is Clint Eastwood

Not working examples

name = eastwood cl
no suggestion

name = jamie curtis
no suggestions

有没有办法让 azure 搜索不太严格，以便为两个不工作的示例提供建议？

Answer 1

这是自动完成的常见用例。我的解决方案是在将内容提交到索引之前对内容进行令牌轮换。然后，您的建议将基于旋转版本而不是名称。

{
"value": [
    {
        "@search.action": "mergeOrUpload",
        "Id": "1",
        "Name": "Clint Eastwood",
        "Rotated": ["Clint Eastwood", "Eastwood Clint"]
    },
    {
        "@search.action": "mergeOrUpload",
        "Id": "2",
        "Name": "Jamie Lee Curtis",
        "Rotated": ["Jamie Lee Curtis", "Lee Curtis Jamie", "Curtis Jamie Lee"]
    }
]

}

我通常将令牌向左旋转，直到像上面那样。请注意，这不会解决您获得输入 jamie curtis 的建议的要求。但是，您可以通过生成额外的令牌迭代来解决这个问题。
