选择特定索引字段我希望在"comment_count"= 1
MongoDB中
我已经试过此查询上,例如特定的索引只选择了“thetext”字段:
db.getCollection('mongotesi').find({},{'bug.long_desc.1.thetext':'1'})
我想秀所有的“thetext”字段也是如此。 这是JSON结构:
{
"_id" : ObjectId("5613c8acc8e53ab811000083"),
"@attributes" : {
"version" : "4.4.10",
"urlbase" : "https://bugs.documentfoundation.org/",
"maintainer" : "[email protected]"
},
"bug" : {
"bug_id" : "31585",
"creation_ts" : "2010-11-12 08:55:00 +0000",
"long_desc" : [
{
"@attributes" : {
"isprivate" : "0"
},
"commentid" : "194230",
"comment_count" : "0",
"attachid" : "40242",
"who" : "eric.moret",
"bug_when" : "2010-11-12 08:55:52 +0000",
"thetext" : "Created attachment 40242ooo base fileI am running ooo 3.2.1 OOO320m18 (Build:9502). I am using an odb bas file to perform a mail merge on an odt file under writer. In the mail merge Wizard, on hitting Next in step 6. (Edit Document), the Status window - creating document opens up and generates my mailing. The crash happens reliably while performing this task.

},
{
"@attributes" : {
"isprivate" : "0"
},
"commentid" : "194232",
"comment_count" : "1",
"attachid" : "40243",
"who" : "eric.moret",
"bug_when" : "2010-11-12 08:56:29 +0000",
"thetext" : "Created attachment 40243ooo write file"
},
],
}
}
我问昨天的东西非常相似,答案是否定的,蒙戈不支持这个呢。如果你喜欢,我可以为你提供参考和工具。 –

不是返回确切的键值,而是使用[slice]返回特定的位置数组。 – Yogesh
