What does "distinct" mean in this context?
I am (was?) using DISTINCT to say, only add the unique fields. As
implemented, it keeps a Collection<String> for each field name. If
the 'mode' is 'DISTINCT' the collection is Set<String>, otherwise
List<String>
There is a lot of processing going on inside Document Builder.
Once you get to the UpdateCommand, you have already lost some
information (copyFields have executed, some things have been converted
to index form, etc).
I noticed that! It made sense when I was implementing this in a
RequestHandler, but it gets a little wonky inside the UpdateHandler -
as you said, copyFields already executed.
I think the best thing is to make a new command that does not directly
take a lucene document as its input. perhaps:
http://svn.lapnap.net/solr/solrj/src/org/apache/solr/client/solrj/SolrDocument.java
http://svn.lapnap.net/solr/solrj/src/org/apache/solr/client/solrj/impl/SimpleSolrDoc.java
Then the UpdateHandler would open the DocumentBuilder merge the
existing document with the passed in document using whatever method
specified.
I would think one would also want to specify things per field.
- append this value to this field
- increment the value of this field
- append this value to this field
- overwrite this field
How would you feel about an interface like this:
public class IndexDocumentsCommand
{
public enum MODE {
APPEND, // add the fields to existing fields
OVERWRITE, // overwrite existing fields
INCREMENT, // increment existing field
DISTINCT // same as APPEND, but make sure there are distinct values
};
// optional id in "internal" indexed form... if it is needed and not supplied,
// it will be obtained from the doc.
public String indexedId;
public Collection<SolrDocument> docs;
public boolean allowDups;
public boolean overwrite;
public SimpleOrderedMap<MODE> modifyFieldMode; // What to do for
each field. We should support *
public int commitMaxTime = -1; // make sure these documents are
committed within this much time
}
