You can use the Predict
parameter to instruct 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
, 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
, 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, IDOL Server returns the exact number of total results.
If you do not want IDOL Server to display the number of results for each database, you can set the TotalResultsPrintDatabase
configuration parameter to False
.
