RE: DataimportHandler development issue

2011-01-21 Thread Derek Werthmuller 
It seems the proper xpath statement to select the href for the link child
when rel="self" is
/feed/link[@rel='self']/string(@ref) for the root

/feed/entry/link[@rel='alternate']/string(@ref) should get the childern .

But it doesn't work in the DIH, does work on other xpath query processors.

Can the DIH handle compound xpath statements?

Your problem is the second entity in the DIH configuration file. The Solr
schema defines the unique key to be the field "link". As noted in the
comments in schema.xml, this means that this field is required.
Solr is not able to populate the "link" field from the Atom feed. I have not
tracked down why this is so, but it is probably because there is more than
one link node under /feed/entry, and the "link" field is not multi-valued.
Change the xpath to, say, "/feed/entry/id", and the import works. Also,
while this is not necessarily an issue, please note that several other
fields have incorrect xpaths for this entity.

To answer your other question, this way of importing data should work fine.

DataimportHandler development issue

2011-01-13 Thread Derek Werthmuller 
We're just getting started with Solr and are very interested in using Solr
for search applications.

I've got the rss example working 1.4.1 didn't work out of the box, but we
figured it out -then found fixes in the svn.  Any way we are learning how
to load the data/rss & atom feeds into the Solr index.  We are trying to
modify the rss-data-import.xml file so that we can import atom feeds also.
But for some reason they don't load.  Here is what we have for the
configuration.  

We've been using the DataImportHandler Development Console
http://localhost:8983/solr/rss/admin/dataimport.jsp?handler=/rssimport
  to
look at the status and the DocsNum but only the rss feed works.
If we remove all the slashdot -rss entity the atom example still doesn't
work.  We've tried creating a seperate atom-data-config.xml file and adding
the 
proper entry to the solrconfig.xml to support the extra dataimport.  That
gave us the same results.

This response format is experimental. It is
likely to change in the future.




Its not clear why its not working.  Advice?
Also is this the best way to load data?  We intent on loading several
thousand docbook documents once we understand how this all works.  We stuck
with the rss/atom example since we didn't want to deal with schema changes
yet.
Thanks
Derek
