Asp.Net核心3.1-使用Ajax搜索一个短语并建议5个类似的短语？

<input type="text" id="searchInput" />
<div id="suggestions"></div>

$(document).ready(function() {
    $('#searchInput').keyup(function() {
        var phrase = $(this).val();
        $.ajax({
            url: '/search',
            type: 'GET',
            data: { phrase: phrase },
            success: function(data) {
                showSuggestions(data);
            }
        });
    });
});

function showSuggestions(suggestions) {
    var suggestionsDiv = $('#suggestions');
    suggestionsDiv.empty();
    $.each(suggestions, function(index, suggestion) {
        suggestionsDiv.append('<div>' + suggestion + '</div>');
    });
}

[HttpGet("/search")]
public IActionResult Search(string phrase)
{
    // 根据短语进行搜索，并获取类似的短语数据
    var similarPhrases = GetSimilarPhrases(phrase);

    return Json(similarPhrases);
}

private List<string> GetSimilarPhrases(string phrase)
{
    // 实现获取类似短语的逻辑
    // ...

    return similarPhrases;
}
