请问 sequoiadb 如何创建索引？有没哪位大神知道啊。
安装 sequoiadb ，创建了一个测试库 testdb ，一个测试集合 test， 用java启动100个线程，插入了1亿条记录, 每秒插入约4000条记录, 总共 花了大约7个小时. 现在测试查询性能. 执行下面的查询花了 79秒, 估计是没创建索引的原因. 谁知道sequoiadb 如何创建索引呢?
哪里有sequoiadb 使用的相关文档啊？
db.testdb.test.find({"email":"a0@qq.com", "name":{$lt:"Tom-99990501"}}).sort({name:-1}).limit(5);
{
"_id": {
"$oid": "55151f04e4b0997b234a4ebf"
},
"name": "Tom-99990401",
"age": "10",
"email": "a0@qq.com"
}
{
"_id": {
"$oid": "55151f02e4b0997b234a27b9"
},
"name": "Tom-99990301",
"age": "10",
"email": "a0@qq.com"
}
{

},
"name": "Tom-99990201",
"age": "10",
