daraです。
"photo:"のようなクエリでSEGVが発生しました。
再現する条件がやや複雑で、手元では、
- 対象のレコードが1件のみの場合は再現しませんでした。
- "photo: OR photo" や "photo: OR abc" 、 "photo: abc" でも再現します。
- "photo OR photo:" の場合は再現しませんでした。
groonga commit 00c4049bf9712ee164b02bb9d9d72115a3f0d441、
Ruby/groonga r668 です。
以下のようなコードで確認しています。
#!/usr/bin/env ruby
$KCODE='u'
require 'groonga'
Groonga::Database.create(:path => 'db/groonga')
Groonga::Schema.define do |schema|
schema.create_table("data", :type => :hash) do |table|
table.text("text")
table.time("time")
end
schema.create_table("terms",
:type => :patricia_trie,
:key_normalize => true,
:default_tokenizer => "TokenBigram") do |table|
table.index("data.text")
end
end
data = Groonga::Context.default['data']
data.add('1', :text => "photo: one two", :time => 0)
data.add('2', :text => "photo: one two", :time => 0)
results = data.select { |r| r['text'].match "photo:" }
実行結果は以下の通りです。
