Hi Adam,

I'm working on exactly such a feature. It'll loop through a view
result-set and query an external script if a document should make it
into the final output or not.

I hope to get some code out this weekend, but it'll be alpha quality and

definitely not ready for general consumption.

Cheers,
 Volker

Hi,

I've just started taking a look into the external capabilities of

couchdb, with the hope that it may provide a solution for what I want

to achieve.

I have a view which is used for every account to render documents only

belonging to that account. The max no. of documents per account is

1000. Each document has a title and a description and I'd like for the

account holder to be able to search these two fields.

My view is along these lines:

function(doc) {
    text = (doc.title + " " + doc.description).toLowerCase();
    emit([doc.project_id, text], null);
}

So _view/Document/all gives me the following result:

{"total_rows":1000,"offset":0,"rows":[

{'id': 12345, 'key':[12345, 'title text plus description'], 'value': null},

    { ... },
    { ... }
  ]
}


Is there any way to pass on this view result to an external script

where it can be parsed for the query string and returned and then have

the view parameters (startkey endkey limit etc) applied?

I am aware of couchdb-lucene and have tried it out. It's a brilliant
project but is a bit of an overkill for my specific requirement.

Many thanks in advance

Adam Groves

PS: Where can I find some nice external code examples? The only ones
I'm aware of to date are the python example on the wiki, the java

examples in the various couch lucene/solr projects and a ruby example

in CouchObject.
