the minimum and maximum number of total (i.e. ignoring
MAX) result rows that will be returned. In
cases where the exact number of result rows is not yet known (e.g.
post-processing is required), the two will differ. If the upper or
lower limit is not known (e.g. a completely unindexed query), one or
both variables will be negative. If both variables are equal, the
total row count is exact.
similar, but are the min/max total rows matched - i.e. by the
WHERE clause, before any reduction by likeprows,
GROUP BY etc.
$sqlresult.indexcount is the same as
