ElasticSearch: query a deep date field using an hours-range filter independent date

How can I query all the advert using the field
("group": { "times": [{"startTime", "startTime"}]})
no matter the date is, query is base on hours-range.
My index is like (for example "startTime": "2016-12-13T09:00:00+08:00",
"endTime": "2016-12-13T22:00:00+08:00", but I just care about the "09:00:00" and "22:00:00"):

Querying field value in MongoDB Document

I have a document embedded in another document. I am able to get the values of the parent but not the inner document. (The commented line gives an error). Below is the code.
DB db = mongoClient.getDB("events");
DBCollection coll = db.getCollection("usercomment");
BasicDBObject searchQuery = new BasicDBObject("source", "twitter").append("data.id_str", "641400902545024");
DBCursor cursor = coll.find(searchQuery);
while(cursor.hasNext()) {
DBObject currDocument = cursor.next();
BasicDBObject newDocument = new BasicDBObject("data", currDocument.get("data"));
//System.out.println(currDocument.get("data.user.location").toString());
System.out.println(currDocument.get("companyName").toString());
}
Below is the json as in Mongo (value of currDocument that I get in Debug):
{
"_id": {
"$oid": "55eff71de4b0b91376cb5920"

How to get the field values from the nested jsons here?

Have you tried pulling each node one by one as it follows.
I suppose you want to get "data.user.location"
BasicDBObject newDocument = new BasicDBObject("data", currDocument.get("data"));
System.out.println(((DBObject)newDocument.get("data")).get("location"));

elasticsearch nested filters are not working as expected

Am applying filter like this using transport client.
{
"bool" : {
"must" : [ {
"nested" : {
"query" : {
"bool" : {
"must" : {
"terms" : {

}
},

}
}, {
"terms" : {
"Assignee DisplayName" : [ "Mateen Khan" ]
}
} ]
}
}
Even after applying filter Am getting data of other sprints also. which means am getting data for "sprint 7" as well as other sprints also. Am using transport client and also Am performing few complex aggregations with in the same query.

Category Search using Foursquare returns wrong Category

I'm doing a category search for food but I'm getting things like Bridges back. Can somebody please verify I'm structuring the URL correctly and if so, possibly point out what I'm doing wrong?
Thank you so much in advance.
URL (blocked out the sensitive stuff like client id and secret):
https://api.foursquare.com/v2/venues/search?client_id=PUT_YOUR_CLIENT_ID_HERE&client_secret=PUT_YOUR_CLIENT_SECRET_HERE&v=20140714&ll=40.7,-74&radius=1000&category=4d4b7105d754a06374d81259
The category ID I'm using is from foursquare's website. It's the ID for 'Food'
You can see the list of IDs Right Here

Please check foursquare venues search parameters correctly, you used "category" parameter but the correct parameter is "categoryId" (not categoryid). So you should change your url to:
https://api.foursquare.com/v2/venues/search?client_id=PUT_YOUR_CLIENT_ID_HERE&client_secret=PUT_YOUR_CLIENT_SECRET_HERE&v=20140714&ll=40.7,-74&radius=1000&categoryId=4d4b7105d754a06374d81259

GSON and Google Drive Java API - “Expected BEGIN_OBJECT but was BEGIN_ARRAY”?

I am trying to serialize and deserialize this FileList object by using Gson. The classes can be found from here:
https://developers.google.com/resources/api-libraries/documentation/drive/v2/java/latest/com/google/api/services/drive/model/FileList.html
and
https://developers.google.com/resources/api-libraries/documentation/drive/v2/java/latest/com/google/api/services/drive/model/File.html
This is how I'm doing it:
private List<File> mListOfResults = new ArrayList<File>();
FileList fileList = new FileList();
fileList.setItems(mListOfResults);
outState.putString("RESULT_LIST", new Gson().toJson(fileList));
and this is how I'm trying to unserialize it:
Type collectionType = new TypeToken<FileList>(){}.getType();
FileList fileList = new Gson().fromJson(savedInstanceState.getString("RESULT_LIST"), collectionType);
Here's the JSON:

I could really use some help with this, as I've been stuck with this problem for 2-3 weeks with my school colleague.
EDIT: I managed to serialize and deserialize FileList object, but now a new problem occurs when I try to get a specific File from deserialized FileList. The serialisation works if I don't add FileList's items to a List. Below is the error that I'm receiving.
Caused by: java.lang.ClassCastException: java.util.LinkedHashMap cannot be cast to com.google.api.services.drive.model.File
Thanks a lot for your time.
