First, you have to add the following references:
- Microsoft.Sharepoint
- Microsoft.Sharepoint.Search
Second:
DataTable resultsDataTable = new DataTable();
using (SPSite site = new SPSite("http://server"))
{
KeywordQuery query = new KeywordQuery(site);
query.QueryText = queryText;
query.ResultTypes = ResultType.RelevantResults;
ResultTableCollection resultTables = query.Execute();
if (resultTables.Count > 0)
{
ResultTable relevantResults = resultTables[ResultType.RelevantResults];
resultsDataTable.Load(relevantResults, LoadOption.OverwriteChanges);
}
}
return resultsDataTable;
In WSS the only ResultType possible is RelevantResults but you have to define it with the following statement:
query.ResultTypes = ResultType.RelevantResults;
If you don't do that the ResultTableCollection doesn't return any ResultTable.
The properties returned are:
- Work ID
- Rank
- Title
- Author
- Size
- Path
- Description
- Write
- SiteName
- CollapsingStatus
- HitHighlightedSummary
- HitHighlightedProperties
- ContentClass
- IsDocument
- PictureThumbnailURL
If you want you can control exactly what properties are returned by adding properties to the StringCollection – query.SelectProperties
…
query.SelectProperties.Add("title");
query.SelectProperties.Add("size");
In the previous example only the Title and the Size are returned.
If you want you can page the results:
int pageSize = 3;
int page = 0;
…
query.StartRow = page * pageSize;
query.RowLimit = pageSize;
You can sort the results by adding items to the SortCollection list.
…
query.SortList.Add("Rank", SortDirection.Ascending);
query.SortList.Add("WorkId", SortDirection.Descending);
I don't know why but it seems that only the first sort item works. I tried to change the direction and also the property of the second sort item but the results were always ordered the same way.
