I'm using couchdb-lucene to index a list of fields (user defined) in a
document using the following design document:
{
"_id": "_design/foo",
"_rev": "16-dcd0d39369c35b3d74ceef13a388826f",
"fulltext": {
"by_metadata": {
"index": "function(doc) {
var ret=new Document();
if (doc['type'] == 'CSAsset' && doc['deleted'] != true) {
for (var i in doc.metadata) {
if(doc.metadata[i]['key'] == 'Title') {
ret.add(doc.metadata[i]['value'].toLowerCase(), {'field':'sort_title',
'store':'yes', 'index' : 'not_analyzed'});
}
ret.add(doc.metadata[i]['value'],{'field':doc.metadata[i]['key'].toLowerCase()
});
ret.add(doc.metadata[i]['value']);
}
for (var i in doc.partitions) {
ret.add(doc.partitions[i].partition_id,{'field':'partition'});
ret.add(doc.partitions[i].partition_id);
}
ret.add(doc['created_at'], {'field':'sort_created_at', 'store':'yes', 'index' :
'not_analyzed'});
return ret;
} else {
return null;
}
}"
}
}
}
(I've formatted the definition so that it's not all on one line for readability
here)
However, when using the by_metadata view it doesn't appear to be breaking the
values up when there are underscores. For instance, searching for the term
"wonderland" should return back a document where there is a field with the
value "some_wonderland_example" but it doesn't. It returns the document if I
search for the full term.
I'm just wondering whether I'm defining the index incorrectly? (of course, feel
free to point out if I'm doing anything else glaringly obviously wrong too!)
