| Subject: | approximate_result_count() always returns zero |
Hi,
When approximate_result_count() is called without calling neither results() nor next_result(), approximate_result_count() always returns zero.
use WWW::Search;
$engine = new WWW::Search("Backend");
$engine->native_query("keyword");
print $engine->approximate_result_count();
In order to avoid this problem, I propose the attached change.
Regards,
