Output Views

Output views are used to format search results returned by the Search Server. Rows are returned in IDT format when no output view has been specified or in a different format when an output view has been defined.

Output Views are also used to inject search statistics into the output.

Statistical Fields

When the following field names are specified in the output view, the Search Server will provide statistics gathered during the search process.

Note that some data in the output of a search is specific to each row. For example, the score is a property that changes for each row. Other statistics are relevant to the search set as a whole. For example, the number of candidates selected is the same for each row returned because it is a property of the set.

Also note that it is not normally possible to retrieve search statistics if the search does not return any rows. In this case, a dummy IDT row (filled with asterisks) can be returned, solely as a vehicle to return the statistics. This feature is enabled with the

Option,
