Highlights 属性仅包含完整字段值的一部分。如果要显示完整的字段值,则必须将突出显示合并到字段值中。
这里有一个对我有用的片段:
public static string Highlight<T>(string fieldName, SearchResult<T> fromResult) where T : class
{
var value = fromResult.Document.GetType().GetProperty(fieldName).GetValue(fromResult.Document, null) as string;
if (fromResult.Highlights == null || !fromResult.Highlights.ContainsKey(fieldName))
{
return value);
}
var highlights = fromResult.Highlights[fieldName];
var hits = highlights
.Select(h => h.Replace("<b>", string.Empty).Replace("</b>", string.Empty))
.ToList();
for (int i = 0; i < highlights.Count; i++)
{
value = value.Replace(hits[i], highlights[i]);
}
return value;
}
对于 ASP.Net MVC
public static MvcHtmlString Highlight<T>(this HtmlHelper htmlHelper, string fieldName, SearchResult<T> fromResult) where T : class
{
var value = fromResult.Document.GetType().GetProperty(fieldName).GetValue(fromResult.Document, null) as string;
if (fromResult.Highlights == null || !fromResult.Highlights.ContainsKey(fieldName))
{
return MvcHtmlString.Create(htmlHelper.Encode(value));
}
var highlights = fromResult.Highlights[fieldName];
var hits = highlights
.Select(h => h.Replace("<b>", string.Empty).Replace("</b>", string.Empty))
.ToList();
for (int i = 0; i < highlights.Count; i++)
{
value = value.Replace(hits[i], highlights[i]);
}
return MvcHtmlString.Create(htmlHelper.Encode(value).Replace("<b>", "<b>").Replace("</b>", "</b>"));
}
在视图中,您可以像这样使用它:
@model SearchResult<MySearchDocument>
@Html.Highlight(nameof(MySearchDocument.Name), Model)
