				curl -XPOST http://localhost:9200/information/news/ -d'
{"title": "越南胡志明游记·教堂·管风琴的天籁之音","content":"这是我平生第一次去教堂，也是第一次完整的参加宗教仪式。当我驻足教堂外的时候，耳边传来天籁之音，是管风琴，确切的说是电子风琴。真正的管风琴造价昂贵，管风琴通常需要根据教堂尺寸定制，无法量产。我记得中国只有4座管风琴，深圳音乐厅有一座。"}

curl -XPOST http://localhost:9200/information/news/ -d'
{"title": "越南胡志明游记·信仰·法事","content":"佛经的形成过程是与佛教的发展相始终的，按照佛教发展的时间顺序，最早形成的是小乘佛教三藏，之后形成的是大乘佛教三藏，最后形成的是密宗三藏。"}
