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
