It is correct that the GSearch operation gfindObjects goes directly to the
Lucene index. That is one option you have, in addition to the option you have
by going directly to Solr with a search url. The Solr search allows you to do
facetted search as well, using that same Lucene index. If that operation should
have gone through GSearch, it would only mean added overhead. GSearch has in
addition the operation browseIndex, which Solr does not have. (To complete the
picture, the GSearch operation updateIndex makes it easier for you to create
Solr index documents from foxml records, than if you had to write the code for
that yourself.)

Hi Nigel,
Thank you very much for your answer.
Finally I think I have to switch the search directly to solr.
I have had a look at the source code of the gsearch/solr plug-in that is in the
package
dk.defxws.fgssolr
It seems to me that Gsearch accesses directly the lucene index on the
filesystem that is configured in the the parameter
fgsindex.indexDir
in the index.properties
In other words, it seems that GSearch doesn’t use SOLR for searching at all. Is
this actually the case?
Regards
Alessandro

Hi Alex,

That interface I like to have the results trough gsearch with in addition
some facet information that comes from solr.

Faceting is not available in GSearch however does support basic search.
Faceting data can be retrieved from SOLR using plugin like
http://wiki.apache.org/solr/Solrj.
We have similar requirement and decided to keep GSearch for managing
indexing related tasks, and developed an interface which uses Solrj to
handle faceting and other search features.
Take a look at some of the community developed search interfaces, some of
them support faceting:
