Predict Parameter

You can use the Predict parameter to instruct HPE IDOL Server to use statistical sampling to estimate the total number of results that are available. You must also set TotalResults to True for your query action. Prediction can increase the query speed.

If you set Predict to False, HPE IDOL Server counts all results and in addition prints the number of results for each database. For example:

http://IDOLhost:IDOLport/action=Query&Text=A fast sports car&TotalResults=True&Predict=True

In this example, if you have set TotalResultsPredictionThreshold to 100, HPE IDOL Server uses statistical sampling to estimate the total number of results that are available for the query. If fewer than 100 results are available for the query, HPE IDOL Server returns the exact number of total results.

If you do not want HPE IDOL Server to display the number of results for each database, you can set the TotalResultsPrintDatabase configuration parameter to False.
