Perl 5.8.4 Linux atlantis 2.4.28-vs1.29 #1 Di Nov 30 10:40:17 CET 2004 i686 GNU/Linux When I make a query, I sometimes get a log(0) runtime error: Debugger excerpt: Plucene::Search::Similarity::idf(/usr/share/perl5/Plucene/Search/Similarity.pm:60): 60: my ($x, $y) = ($docs->doc_freq($tf), $docs->max_doc); DB<4> v 57 58 sub idf { 59: my ($self, $tf, $docs) = @_; 60==> my ($x, $y) = ($docs->doc_freq($tf), $docs->max_doc); 61: return 1 + log($y / (1 + $x)); 62 } 63 64 =head2 coord 65 66 DB<4> x 0 0 DB<5> x $self 0 'Plucene::Search::Similarity' DB<6> x $tf 0 Plucene::Index::Term=HASH(0x8bf0a8c) 'field' => 'content' 'text' => 'greate' DB<7> x $docs 0 Plucene::Search::IndexSearcher=HASH(0x8be1e5c) 'reader' => Plucene::Index::SegmentsReader=HASH(0x8b67abc) 'directory' => 'name' 'max_doc' => 0 'readers' => ARRAY(0x87688e4) empty array 'writelock' => undef DB<8> n Plucene::Search::Similarity::idf(/usr/share/perl5/Plucene/Search/Similarity.pm:61): 61: return 1 + log($y / (1 + $x)); DB<12> x $x 0 undef I suspect that the index is empty at this point (I have added two docs with a writer prior to this query, but the writer has not yet been closed).
