daraです。
"a OR b OR c OR d OR e OR f OR g OR h OR i" のような
長いクエリでselectするとSEGVが発生するようです。
groonga commit 6f1092858e9eafd5bfd954e24a512c91339418e1
Ruby/groonga r667
で試しています。
以下のようなコードで確認しました。
#!/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 => "test one two", :time => 0)
results = data.select { |r| r['text'].match "a OR b OR c OR d OR e OR
f OR g OR h OR i" }
実行結果は以下の通りです。
