Marvin Humphrey commented on LUCY-184:
--------------------------------------
For a workaround that works right now, you can simply wrap the IndexSearcher
constructor in an eval:
{noformat}
my $searcher = eval { Lucy::Search::IndexSearcher->new(index => $index) };
return unless $searcher;
...
{noformat}
This is similar to one of the library-level options, which is adding an open()
class method to IndexSearcher which returns false and sets Lucy->error instead
of throwing an exception.
> Exception is thrown when searching an empty index.
