Temp_Index_Max_Doc=10000
allows a single NotesDatabase or NotesDocumentCollection "FTSearch" running on a server to return up to 10000 entries.
To use the Temp_Index_Max_Doc setting for an agent running on a server, you must also use the FT_Max_Search_Results setting and specify the same value, for example
FT_Max_Search_Results=10000
For a database that is not indexed and is running in an agent on the server, you must set the Temp_Index_Max_Doc Notes.ini variable as well. The absolute maximum is 2,147,483,647
The Notes.ini variable FT_Max_Search_Results overrides this limit for indexed databases or databases that are not indexed but that are running in an agent on the client
