FindOptions.ThresholdScore Property

FindOptions.ThresholdScore Property

The score below which results should not be returned. The valid range is 0 through 1 (worst to best).

Public ThresholdScore As System.Double = 0.85


[C#]

public System.Double ThresholdScore;

Remarks

• The ThresholdScore property default is the MapPointConstants.FindScoreThreshold property (0.85).

• The FindResult.Score property identifies a find result in terms of how well it matches the search criteria.

• If the find results do not include the entities you expect, try lowering the ThresholdScore property. Set it to 0 to return all results. For example, to find the 50 U.S. states, set the FindSpecification.EntityTypeNames property to "AdminDivision1", the SearchContext property to "244", and the ThresholdScore property to "0".

• The ThresholdScore property is ignored when passed for the points of interest find methods (FindServiceSoap.FindByID, FindServiceSoap.FindByProperty, FindServiceSoap.FindNearby and FindServiceSoap.FindNearRoute).

'Return all results
Dim findSpec As New FindSpecification()
findSpec.DataSourceName = "MapPoint.NA"
findSpec.InputPlace = "Seattle, WA"
findSpec.Options = New FindOptions()
findSpec.Options.ThresholdScore = 0

Dim foundResults As FindResults
foundResults = findService.Find(findSpec)

Dim fr As FindResult
For Each fr In foundResults.Results
 Console.WriteLine(fr.FoundLocation.Entity.DisplayName)
Next



[C#]

//Return all results
FindSpecification findSpec  = new FindSpecification();
findSpec.DataSourceName = "MapPoint.NA";
