Beginning with Domino 5.0, two reserved Notes fields are available for displaying the number of documents found.
Hits: Actual number of results returned this page, may be less than Count requested. This field is useful in determining the Start parameter for a Next button.
TotalHits:Total number of hits found by the search.
The field TotalHits will return a total including documents that contain Readers fields which restrict the currently logged on web user from viewing the documents. The field Hits will not include Readers field restricted documents.
Some say document.links.length will return the number of hits, but this method is very proved to be very inconsistent for me. These 2 new fields make it a snap now!
This info was from the R5 Designer Help, document "Customizing Search Forms."
