Hi,  
[ES VERSION: 1.0.1. Default mappings.]

I have an index which holds the twitter data. The user will have the option  
to perform the [https://twitter.com/search-advanced](https://twitter.com/search-advanced) in the UI that I'm  
building. Upon receiving the search request, I query the index and return  
the results. [Source: [http://pastebin.com/ep0eBxXY](http://pastebin.com/ep0eBxXY)]

I have a couple of questions:

1. How do we query complex objects? ie., if i am interested in a field  
which is within another object.  
Object A  
Field in Object A

- Object B
  - Field in Object B

1. For me, even the OR, AND and NOT queries doesn't seem to work. Am I  
missing anything?

request.getAllOfTheseWords().split(",");  
FilterBuilder[] allWordsFilter = new  
FilterBuilder[allWords.length];  
for(int i=0;i\<allWords.length;i++){  
String word = allWords[i];  
allWordsFilter[i] =  
FilterBuilders.termFilter("text", word);  
}

srb.setQuery(QueryBuilders.filteredQuery(QueryBuilders.matchAllQuery(),  
FilterBuilders.andFilter(allWordsFilter)));  
}  
else if(null!=request.getOrWords()){  
String[] orWords = request.getOrWords().split(",");  
FilterBuilder[] orFilters = new  
FilterBuilder[orWords.length];  
for(int i=0;i\<orWords.length;i++){  
String word = orWords[i];  
orFilters[i] = FilterBuilders.termFilter("text",  
word);  
}

srb.setQuery(QueryBuilders.filteredQuery(QueryBuilders.matchAllQuery(),  
FilterBuilders.orFilter(orFilters)));  
}  
else if(null!=request.getNoneOfTheseWords()){  
String[] noneOfTheseWords =  
request.getNoneOfTheseWords().split(",");  
FilterBuilder[] noneOfTheseWordsFilter = new  
FilterBuilder[noneOfTheseWords.length];  
for(int i=0;i\<noneOfTheseWords.length;i++){  
String word = noneOfTheseWords[i];  
noneOfTheseWordsFilter[i] =  
FilterBuilders.termFilter("text", word);  
}

srb.setQuery(QueryBuilders.filteredQuery(QueryBuilders.matchAllQuery(),  
FilterBuilders.notFilter(FilterBuilders.orFilter(noneOfTheseWordsFilter))));  
}  
else if(null!=request.getHashTags()){  
String[] hastags = request.getHashTags().split(",");  
FilterBuilder[] hashTagFilter = new  
FilterBuilder[hastags.length];  
for(int i=0;i\<hastags.length;i++){  
String hashtag = hastags[i];  
hashTagFilter[i] =  
FilterBuilders.nestedFilter("hashtag",  
FilterBuilders.termFilter("hashtag\_text", hashtag));  
}

srb.setQuery(QueryBuilders.filteredQuery(QueryBuilders.matchAllQuery(),  
FilterBuilders.orFilter(hashTagFilter)));  
}  
else if(null!= request.getFromUser()){

srb.setQuery(QueryBuilders.filteredQuery(QueryBuilders.matchAllQuery(),  
FilterBuilders.termFilter("screen\_name", request.getFromUser())));  
}  
else if(null!=request.getSince() &&  
null!=request.getUntil()){

srb.setQuery(QueryBuilders.filteredQuery(QueryBuilders.matchAllQuery(),  
FilterBuilders.rangeFilter("created\_at").from(request.getSince()).to(request.getUntil())));  
}  
}

However this works fine.

Please help me out.

Thanks

ES flattens out your inner objects/fields into individual fields. So for  
example, you can reference any inner object field using the fully qualified  
path to it, like:

{ "a": { "b": { "c": "value" } } }

And the c field can be accessed using the following field name:

"a.b.c"

And you can do a match, term, or any other query/filter using the above  
field name.
