Ryan McKinley commented on SOLR-139:
------------------------------------
Is this what you are suggesting?
I added a second searcher to DirectUpdatehandler2 that is only closed when you
call commit();
// Check if the document has not been commited yet
Integer cnt = pset.get( id.toString() );
if( cnt != null && cnt > 0 ) {
commit( new CommitUpdateCommand(false) );
}
if( committedSearcher == null ) {
committedSearcher = core.newSearcher("DirectUpdateHandler2.committed");
}
Term t = new Term( uniqueKey.getName(), uniqueKey.getType().toInternal(
id.toString() ) );
int docID = committedSearcher.getFirstMatch( t );
if( docID >= 0 ) {
Document luceneDoc = committedSearcher.doc( docID );
// set the new doc as the existingDoc + our changes
DocumentBuilder builder = new DocumentBuilder( schema );
add.doc = builder.bulid(
this.modifyDocument( luceneDoc, cmd.doc, cmd.mode ) );
}

This passes a new test that adds the same doc multiple times. BUT it does
commit each time.
Another alternative would be to keep a Map<String,Document> of the pending
documents in memory. Then we would not have to commit each time something has
changed.

> It would be nice to be able to update some fields on a document without
> having to insert the entire document.
> Given the way lucene is structured, (for now) one can only modify stored
> fields.
> While we are at it, we can support incrementing an existing value - I think
> this only makes sense for numbers.
