Nested Array Document Query (similar to @tsolakp's problem)

Elastic Stack Elasticsearch
1

I imagine tsolakp and I are having the same problem, but I did get a nested query to run on a nested field that's a simple Hash. However, I'm having problem querying a nested document that contains an array of hashes (exactly like obj1 here: http://www.elasticsearch.org/guide/reference/mapping/nested-type.html).

Here's the mapping I've got.

{
"tweet" : {
"properties" : {
"name" : {
"type" : "string"
},
"comments" : {
"properties" : {
"text" : {
"type" : "string"
},
"username" : {
"type" : "string"
},
},
"type" : "nested"
}
}
}
}

and I indexed this document

{
"name" : "Jane",
"comments" : [
{"text" : "this is text", "username" : "Jane"},
{"text" : "this is more text", "username" : "Jack"}
]
}

I'm trying to search the comments section by username and I've issued the following query:

{
"query" : {
"nested" : {
"path" : "comments",
"query" : {
"bool" : {
"must" : [
{
"text" : {
"comments.username" : "Jane"
}
}
]
}
}
}
}
}

However I'm not getting any hits....

I basically followed the documentation exactly and am not sure why this is happening. Any ideas?

---UPDATE

turns out this query works, but the text query does not still looking into it....

'{
"query" : {
"nested" : {
"path" : "comments",
"query" : {
"query_string" : {
"default_field" : "comments.text",
"query" : "this is more text"}}}}}'

--UPDATE2
I tried a simple text query on comments.text and it returned no hits. I must be missing something about how the text query works...

Both your mapping and your query are not valid jsons (use jsonlint for
example to test that: http://jsonlint.com/). Here is a gist of the valid
ones: gist:1108683 · GitHub.

A note to users posting on the list, it will be much simpler to help you
with gisted curl recreations, and not pasting random bits and pieces into
the mail.

"must" : [

}
]
}
}
}
}
}

However I'm getting a parsing error like this:
Parse Failure [Failed to parse source [{"query" : {"nested" ..........

I basically followed the documentation exactly (after help from @favre) but
am not sure why I'm still getting an error. Any ideas?
