Searching on multi-field fields

Hi,

I have an index with a multi-field field using the example in
http://www.elasticsearch.org/guide/reference/mapping/multi-field-type.html

{
"tweet" : {
"properties" : {
"name" : {
"type" : "multi_field",
"fields" : {
"name" : {"type" : "string", "index" :
"analyzed"},
"untouched" : {"type" : "string", "index" :
"not_analyzed"}
}
}
}
}
}

However, I can't seem to successful query nor perform faceting on the
multi-field.

EG: http://localhost:9200/twitter/tweet/_search?q=name.untouched:*
(using 'name.untouched' as recommended in
http://www.elasticsearch.org/guide/reference/mapping/multi-field-type.html)
returns no results.

Is my syntax incorrect, or does multi-field fields not support
querying (but that would not make sense)?

To provide more detail:

http://localhost:9200/twitter/tweet/_search?fields=name.untouched&q=*
works in that all docs are retrieved with only the name.untouched
field, but http://localhost:9200/twitter/tweet/_search?fields=name.untouched&q=name.untouched:*
does not work.

Is this a bug?

You can't ask for name.untouched to be returned as its not stored, and not
part of the json to be extracted from. When you ask for a field to be
returned, it either needs to be stored, or, it needs to be a valid path
"into" the source json document.

Hi Shay,

The name.untouched is stored. When I do q=*, the name.untouched values
do show up in the result set, and I can also limit the returned field
values to only name.untouched via fields=name.untouched.

The problem is that I get an empty result set when I do
q=name.untouched:*

Do I have the incorrect query syntax or maybe this is a bug?

Heya, this seems to work: gist:1296043 · GitHub. Maybe you can
change it to show the problem you are having?

I am also experiencing this same behavior. None of the multi-fields are coming back in a query result. I can view the values in a q=: but if I do a q=parent.child:* it doesn't return anything. This is the exact same behavior explained above in this article. Even when I copy the code at https://gist.github.com/1296043 verbatim, I am still not able to get back any results.

Is there some type of configuration that has to be done?

Thanks!

Here is the test scenario I am trying to conduct:

curl -XPUT localhost:9200/6 -d '{
"mappings" : {
"type1" : {
"properties" : {
"name" : {
"type" : "multi_field",
"fields" : {
"name" : {"type" : "string", "index" : "analyzed"},
"untouched" : {"type" : "string", "index" : "not_analyzed"}
}
}
}
}
}
}'

curl -XPUT localhost:9200/6/type1/1 -d '{
"name" : {"name":"test me","untouched":"test1"}
}'

curl -XPUT localhost:9200/6/type1/2 -d '{
"name" : {"name":"test me","untouched":"test2"}
}'

curl -XPUT localhost:9200/6/type1/3 -d '{
"name" : {"name":"test me","untouched":"test3"}
}'

curl -XPOST localhost:9200/6/_refresh

This returns all 3 documents:

curl -XPUT localhost:9200/6/type1/_search?q=name.untouched:*

This returns nothing:

curl -XPUT localhost:9200/6/type1/_search?q=name.untouched:test3

I think you misunderstood what multi field is for. The idea of multi field
is that for the same json field value (in your case, name), it will be
indexed in two different manners, one under "name", and one under
"name.untouched". In your case, you have two *different" json fields,
"name", and "untouched", with different values. So you should simply have
two different mappings for those.
