From 671840bf2fa63f1e268f96e6830a4a6606b28cf0 Mon Sep 17 00:00:00 2001 From: David Gustafsson Date: Wed, 4 Mar 2020 17:07:11 +0100 Subject: [PATCH] Bug 24807: Add "year" type to improve sorting behaviour Add a "year" search field type. Fields with this type will only retain values that looks like years, so invalid values such as whitespace or word characters will not be indexed. This for instance improves the behaviour when sorting by "date-of-publication". If all values are indexed, records with junk data instead of valid years will appear first among the search results, drowning out more relevant hits. If assigning this field the "year" type these records will instead always appear last, regarless of sort order. To test: 1) Have at least two biblios, one with a valid year in 008 (pos 7-10) and another with an invalid one ("uuuu" for example) 2) Perform a wildcard search (*) and sort results by publication date. 3) The record with invalid year of pulication in 008 should appear first 4) Apply patch and run database updates 5) Reindex ElasticSearch 6) Perform the same search as in 2) 7) The record with the invalid year should now appear last --- Koha/SearchEngine/Elasticsearch.pm | 18 +++++++++++++-- Koha/SearchEngine/Elasticsearch/Indexer.pm | 3 +++ .../elasticsearch/field_config.yaml | 2 ++ .../searchengine/elasticsearch/mappings.tt | 5 +++++ t/Koha/SearchEngine/Elasticsearch.t | 22 ++++++++++++++++++- 5 files changed, 47 insertions(+), 3 deletions(-) diff --git a/Koha/SearchEngine/Elasticsearch.pm b/Koha/SearchEngine/Elasticsearch.pm index 19fa2a47fa..f575e95b08 100644 --- a/Koha/SearchEngine/Elasticsearch.pm +++ b/Koha/SearchEngine/Elasticsearch.pm @@ -37,7 +37,7 @@ use Search::Elasticsearch; use Try::Tiny; use YAML::Syck; -use List::Util qw( sum0 reduce ); +use List::Util qw( sum0 reduce all ); use MARC::File::XML; use MIME::Base64; use Encode qw(encode); @@ -216,6 +216,8 @@ sub get_elasticsearch_mappings { $es_type = 'integer'; } elsif ($type eq 'isbn' || $type eq 'stdno') { $es_type = 'stdno'; + } elsif ($type eq 'year') { + $es_type = 'year'; } if ($search) { @@ -471,7 +473,6 @@ sub _process_mappings { # with differing options for (possibly) mutating data # so need a different copy for each my $_data = $data; - $record_document->{$target} //= []; if (defined $options->{substr}) { my ($start, $length) = @{$options->{substr}}; $_data = length($data) > $start ? substr $data, $start, $length : ''; @@ -479,6 +480,10 @@ sub _process_mappings { if (defined $options->{value_callbacks}) { $_data = reduce { $b->($a) } ($_data, @{$options->{value_callbacks}}); } + if (defined $options->{filter_callbacks}) { + # Skip mapping unless all filter callbacks return true + next unless all { $_->($_data) } @{$options->{filter_callbacks}}; + } if (defined $options->{property}) { $_data = { $options->{property} => $_data @@ -491,6 +496,8 @@ sub _process_mappings { $_data = substr $_data, $nonfiling_chars; } } + + $record_document->{$target} //= []; push @{$record_document->{$target}}, $_data; } } @@ -882,6 +889,13 @@ sub _field_mappings { return $value ?
