The crux of the problem is that updating a field in lucene requires we reindex the *entire* document, not just the single field.
The approach in SOLR-139 assumes you have stored all fields, and loads them then reindexes. After working with this for a while, it is clear that this kind of approach is better tackled on the client side -- where you have better knowledge how the fields may be stored, or could read them from solr if you want. That said... there has been some great new work on a different field type that will potentially be updateable without reindexing the whole document. http://www.slideshare.net/lucenerevolution/willnauer-simon-doc-values-column-stride-fields-in-lucene (i'm actually not sure what it is called anymore) ryan 2011/9/26 Poulton, Gareth | Gareth | DU <[email protected]>: > Hi, > > I’d like to do bulk updating on a single field, i.e. provide a field name > once and then a long list of document ids and values to update only that > field and leaving the others intact.
