Appendix A: Estimated vs. Actual Number
of Results
The Google Search Appliance does not guarantee the ability to return a particular number of results for
any given search query. The total count of results is an estimate of the actual number of results for the
search request. This section covers issues relating to this topic.
In search appliance software version 6.2 and later, the estimated number of results is different
depending on whether filtering is enabled.
• When filtering is not enabled, you see the estimated total number of results.
• When filtering is enabled, for all but the last page of results you see the estimated total number of
results. If you have requested the last page of results, then you see the total number of filtered
results, which is likely to be much smaller than the estimated total number of results.
You can use the rc search parameter to request an accurate result count for up to 1M documents, but it
might introduce high latency.
Counting Results in Secure Search
The total count of search results is not provided when a secure search is performed, regardless of
which type of output format, XML or HTML, is used. A secure search request includes the parameters
access=a or access=s.
