You will need to create a DocumentQuery,and then call AddTextSearchConstraintMethod() on it. A quick example might look like this:
// assumes _application is properly initialized Hyland.Unity.Application
DocumentQuery DocumentQuery docQuery = _application.Core.CreateDocumentQuery();
// Uses IDOL to search for the string "sample"
docQuery.AddTextSearchConstraint( TextSearchType.IDOLFullTextSearch, "sample");
DocumentList results = docQuery.Execute(100);
Of course, you would want to add some document types, keywords or other constraints to the DocumentQuery to make it perform better, but this is the general idea.
If you wanted the "Score" to come back, you would need to add that DisplayColumn to the query and then use ExecuteResults() instead of Execute().
// assumes _application is properly initialized Hyland.Unity.Application
DocumentQuery DocumentQuery docQuery = _application.Core.CreateDocumentQuery();
// Uses IDOL to search for the string "sample"
docQuery.AddTextSearchConstraint( TextSearchType.IDOLFullTextSearch, "sample");
docQuery.AddDisplayColumn(DisplayColumnType.FullTextScore);
using (QueryResult docResults = docQuery.ExecuteQueryResults(100))
{
// loop through results, get display column here
}
There is not a way to retrieve a version of the document with the search results highlighted in yellow via the Unity API.
