I think it's nice for the default solrindex-mapping.xml to include the redundant fields. Personally, I wouldn't have known what fields were available for mapping.
I have not seen any documentation that gives an easy to check list of fields. I guess you could check the Solr schema.xml that comes with Nutch, but the default solrindex-mapping.xml is much more straight forward. -Mark On Sat, May 14, 2011 at 5:13 AM, Gabriele Kahlout <[email protected]>wrote: > On Sat, May 14, 2011 at 12:07 PM, Markus Jelsma > <[email protected]>wrote: > > > > > > > In solrindex-mapping.xml I am mapping lastModified to a field > "changed" > > > > in > > > > > > > > Solr: > > > > <field dest="changed" source="lastModified"/> > > > > > > I bump in with a documentation question (not offering any solution to > the > > > problem): > > > > > > My default expectation is that this mapping is only required to change > > the > > > name. i.e., currently solrindex-mapping.xml doens't define any mapping > > for > > > lastModified and so I assume it'll behave the same as if <field > > > dest="lastModified" source="lastModified"/> was defined (i.e. map to to > > > same name in nutch), but if it was so why is <field dest="content" > > > source="content"/> redundantly listed? > > > > > > Or should one specify every field that wants to end-up in the index > with > > a > > > field entry in solrindex-mapping.xml, somewhat redudant given the > > listings > > > in schema.xml? > > > > It's not required to list every field.
