Working with Data with the MapPoint Web Service Find APIs - Finding more default matches
(Page 4 of 4 )
These results include places from both the United States and Australia. By default, the find threshold score is set to 0.85, which means that any find match with a confidence score of less than 0.85 is not returned. So, to get more results for this query, you can simply decrease the threshold score using the FindOptions.ThresholdScore field:
//Create find options
findspec.Options = new FindOptions();
//Set threshold score to zero
findspec.Options.ThresholdScore = 0;
With the threshold score set to zero, the same query for Redmond yields 32 results of which only the following first 25 are returned:
Redmond, Washington, United States
Redmond, Oregon, United States
Redmond, Western Australia, Australia
Redmond, Larimer, Colorado, United States
Redmond, Butler, Pennsylvania, United States
Redmond, Sevier, Utah, United States
Redmond, Mason, West Virginia, United States

Returning more find results
By default, MapPoint Web Service always returns only 25 results at once, but you can get a maximum of 500 results using the FindOptions.Range field:
//Create find options
findspec.Options = new FindOptions();
//Set result count
findspec.Options.Range = new FindRange();
//Set to the maximum count
findspec.Options.Range.Count = 500;
After adding this code to the Find code, you get all 32 results returned by theFindmethod.
