Hi Kieran
About the search, is perfomed using lucene fields. In the folder
INSTALL_DIR/web/geonetwork/xml/csw/filter-to-lucene.xsl
the query is transformed to another xml format processed by
LuceneSearcher.makeQuery method.
To add additional fields to lucene check the files
INSTALL_DIR/web/geonetwork/xml/schemas/XXXXX/index-fields.xsl .
Also to make the field available in CSW searches, need to add to
INSTALL_DIR/web/geonetwork/WEB-INF/config-csw.xml a section like:
<parameter name="*CSW_Query_Name*" field="*LUCENE_field_name*"
type="AdditionalQueryables">
<xpath schema="iso19139" path="*XPATH_in_iso19139*"/> <!-- Optional:
Used in CSW Transaction -->
</parameter>
Regards,
Jose García

Hello Geonetwork-users,
is there really nobody out there, who have some more information about the
search mechanism implemented in the CSW shipped with the Geonetwork
software?
