Subject couch-lucene hwo to refernce elements in a complex document?
Date Wed, 16 May 2012 20:38:13 GMT
I have couch-lucene working when I index a top level element in my documents. However when
I try and reference a sub element as I would with a couchdb view no results are returned.
A extract from my document is:

{
   "_id": "00023157-c1f8-4e39-ab9a-d56726739b8d",
   "_rev": "1-45cd4f7506ccede344d682904556be4b",
   "type": "maven-build-profile",
   "schema": "TODO-idOfSchemaDocument",
   "headers": {
       "started": 1328795714442,
       "core": {
           "user": "buildadm",
           "ip": "127.0.0.1",
           "executionId": "a607c818-c568-40a9-adbc-0844e6bf9a02"
       }
}
}

The following works

{
   "_id": "_design/lucene",
   "_rev": "19-1c7be47e52f8a65e9bb387e8c3251dd4",
   "language": "javascript",
   "fulltext": {
       "by_type": {
           "index": "function(doc) { var res = new Document(); res.add( doc. type); return
res; }"
       }
   }
}

curl http://127.0.0.1:5999/_fti/local/build-profiles-raw-mk/_design/lucene/by_type?q= maven-build-profile

The following does not:

{
   "_id": "_design/lucene",
   "_rev": "19-1c7be47e52f8a65e9bb387e8c3251dd4",
   "language": "javascript",
   "fulltext": {
       "by_user": {
           "index": "function(doc) { var res = new Document(); res.add( doc.headers.core.user
); return res; }"
       }
   }
}


curl http://127.0.0.1:5999/_fti/local/build-profiles-raw-mk/_design/lucene/by_user?q=buildadm

Log file wise it provides:

2012-05-16 21:33:01,980 WARN [build-profiles-raw-mk] _design/buildstats caused TypeError:

2012-05-16 21:33:01,980 WARN [build-profiles-raw-mk] _design/buildstatsdetail caused TypeError:

now at update_seq 106

I'm sure there is an easy answer to this, but to a javascript/couchdb newbie i'm confused
as to why I can use doc.headers.core.user can be used in my couch map. But not in the above
couch-lucene index.

Thanks

Mike
