Notes Error: Maximum allowable documents exceeded for a temporary full text index

While executing FTSearch method on NotesView class you might get an exception which says "Notes

Error: Maximum allowable documents exceeded for a temporary full text index" 

The exception occurs when Full Text indexing is disabled on the database and the number of items in the database is huge.

When we try to execute a FTSearch method on such a database a temporary Full Text index is created on the database. The number of items which can be indexed by this temporary index is set to some default value and if the number of items in the database exceeds this default value then we get this exception. We can override this setting in server's notes.ini using the following parameter 

TEMP_INDEX_MAX_DOC=number

Once we set this number to a value greater then number of items in the database the API should start working.
