I'm having trouble constructing a filter on a nested type in a document and
was wondering if anyone had any pointers or suggestions:

Why shouldn't the filter match both documents? Both of them contain a
nested document that satisfies the query/filter. Note that elasticsearch
will return the entire contents of the parent document, which will include
all of the nested documents.

Hello.

If i correctly understood your probleme, I think I would solve it with a
"nested filter" encapsulating an "and filter" encapsulating two "range
filters"

Ivan,

Thanks for replying. The filter I included should indeed match both docs,
but the behaviour I am looking for is a filter that would only examine an
individual date's start and end ... essential treating each nested date as
a data set. To put it another way, I want to find any departures that have
a single date with a start gte some_date and an end date lte some_date.

Hey DH,

I figured I probably have to use an "and" filter somewhere but part of my
problem is I am having difficulty figuring out how the nesting works with
the query dsl. I did try this:

{
"query": {
"filtered": {
"query": {"match_all": {}},
"filter": {
"nested": {
"path": "dates",
"query": {
"filtered": {
"query": {"match_all": {}},
"filter": {
"and": [
{"range": {"dates.starts": {"gte":
"2013-11-11"}}},
{"range": {"dates.ends": {"lte":
"2013-12-05"}}}
]
}
}
}
}
}
}
}
}

but that just gave me the same results as the original filtered query.

Yes, indeed.

You got both documents back because your filtered query filter containing
the dates filters brings back all the docs (build on a match_all query)
thats have both dates, not on a per nested doc basis .
Then, you put that in a nested filter but the damage has been done already.
Sorry if I am not clear, english is not my first language.

Try this instead :

{
"filtered" : {
"query" : {
"match_all" : {}
},
"filter" : {
"nested" : {
"filter" : {
"and" : {
"filters" : [{
"range" : {
"dates.starts" : {
"gte" : "2013-11-11"
}
}
}, {
"range" : {
"dates.ends" : {
"lte" : "2013-12-05"
}
}
}

  ]
 }
},
"path" : "dates"

}
}
}
}
