1：建立全文索引

db.article01.ensureIndex( { "$**": "text" },{ name: "TextIndex" });

db.article01.insert({article:"lifeng"});

db.article01.insert({auth:"xxxx",title:"yy"});

db.article01.insert({auth:"lifeng"});

db.article01.find({$text:{$search:"lifeng"}},{score:{$meta:"textScore"}}).sort({score:{$meta:"textScore"}});
