SharePoint 2013 KeywordQuery Search SPField

Question

The SharePoint search service works on documents content and it Metadata (properties), I need to retrieve the field name and it content (SPField) which the search are matched on it.

What field should I add to the SelectProperties object ? or where I can find these information.

KeywordQuery keywordQuery = new KeywordQuery(SPContext.Current.Site);

keywordQuery.QueryText = queryText;
keywordQuery.ResultsProvider = SearchProvider.Default;
var selecProperties = keywordQuery.SelectProperties;
selecProperties.Add("UniqueId");
selecProperties.Add("FileLeafRef");
selecProperties.Add("ListId");
selecProperties.Add("WebId");
selecProperties.Add("Created");
selecProperties.Add("CheckoutUserOWSUSER");

SearchExecutor searchExecutor = new SearchExecutor();
ResultTableCollection resultTableCollection = searchExecutor.ExecuteQuery(keywordQuery);
ResultTable resultTable = resultTableCollection.Filter("TableType", KnownTableTypes.RelevantResults).FirstOrDefault();
DataTable dataTable = resultTable.Table;

Answer 1

我在属性HitHighlightedProperties的KeywordQuery对象中找到了解决方案，所有需要的就是将已爬网的属性（托管属性）添加到SelectProperties和HitHighlightedProperties ，然后在该字段中，您将发现xml在所有可用字段中包含有关found关键字的详细信息。
