Subject Best way to return ExternalFileField in the results
Date Tue, 15 Jul 2008 16:00:37 GMT
Hi all,
I've been trying to return a field of type ExternalFileField in the search
result. Upon examining XMLWriter class, it seems like Solr can't do this out
of the box. Therefore, I've tried to hack Solr to enable  this behaviour.
The goal is to call to ExternalFileField.getValueSource(SchemaField
field,QParser parser) in XMLWriter.writeDoc(String name, Document
document,...) method. There are two issues with doing this:

1) I need to create an instance of QParser in writeDoc method. What is the
best way to do this? What kind of overhead of creating a new QParser for
every document returned?

2) I have to modify writeDoc method to include the internal Lucene document
Id because I need it to retrieve the ExternalFileField:


The immediate affect is that it breaks writeVal() method (because this
method references writeDoc()).

Any comments?

Thanks in advance.
