$indexcount

The $indexcount variable is set when a SQL statement is executed (eg. before the first row is returned). It gives an estimate of how many rows will match the given query: its value is the number of matching rows found in the index(es) used by the query. This is different from $next, which is the exact number of matching rows but is set only after all rows are returned. See the SQL statement (p. ) for details. The $indexcount variable was added Oct. 24 1996. See also $rows.min, $rows.max which supersede $indexcount.
