Got it, however, it is not quite what I was hoping to accomplish.
The language object of the each doc has 12 languages and
include_docs=true will response all of them. What can I do to get all
doc properties but just the language 'fr' property, for example, to save
on data usage on mobile devices?

Yes, the second example I gave should accomplish that.
The {} is an empty JSON object which should sort higher than any value you
emit assuming you're not emitting complicated objects which is not
suggested due to surprising sort results.

Just for clarification, I'm looking after one map function that can create
a view where all docs that have the same doc.kml_id, are sorted by
doc.marker and only contains the description for a particular language from
the doc.language array.
Is this possible with one map function?

And I need the doc.marker too, sorted 0...n? Any example?
What are the {} for?
Thanks again.

A couple examples might be something like:
All rows for French:
startkey: ["fr"]
endkey: ["fr",{}]
All rows for a specific kml_id:
starkey: ["fr", id]
endkey: ["fr", id, {}]

Thanks for your response Paul. I think I'm missing something important.
How do I tell the view that I just need fr - language and not en, de,
es ...
startkey: ["fr", id, 0] ?

You'll need to add an element to the key to emit the language. Pseudo
code:
for language in doc["languages"]:
emit([language, doc.kml_id, doc.marker], 1)
Also note that its generally not a good idea to emit the doc as the
value.
You should prefer to use include_docs=true in the query string.
Emitting
1
allows you to specify "_sum" as a reduce function to get row counts
for
specific start/end key pairs.

Hi there,
this map function
"map": "function(doc) { if (doc.kml_id && doc.marker) {
emit([doc.kml_id,
doc.marker], doc) } }"
and this startkey
startkey: [id, 0] --> sorting doc.marker
let me retrieve data from a couch as needed.
Now I got the task to add more languages beside English for
description
properties in an array structure like this
"language": [
{
"en":{
}
},
{
"fr": {
}
}
]
I stuck in figuring out a startkey that let me retrieve the sorted
data
only for a particular language.
Any advice would be really appreciated.
Thanks,
Stephan
