[GeoNetwork-users] Metadata weight in geonetwork searches

GeoNetwork GeoNetwork User

Hi list,
In our geonetwork catalog, there are metadata created with our geonetwork and metadata harvested from other catalogs.
Currently, harvested metadata are always in the top, partly because there are many more.
Is there a way to give more weight to native metadata of the catalog (i.e. not harvested) so that they are displayed first in search results ?
Maybe using Lucene configuration ?

Thanks for your help
Matthieu

Hi

I think this is what you need:
https://github.com/geonetwork/core-geonetwork/blob/develop/web/src/main/webapp/WEB-INF/config-lucene.xml#L300-L320

I haven't use this feature, but I guess you can use it with the Lucene
field *_isHarvested* that gets the value *y* if it's from a harvested
metadata, to lower the boosting for harvested metadata, probably something
like this should work (check and try with different values for boosts:

<boostDocument
name="org.fao.geonet.kernel.search.function.ImportantDocument">
    <Param name="fields" type="java.lang.String"
value="_isHarvested,_isHarvested"/>
    <Param name="values" type="java.lang.String" value="y,n"/>
    <Param name="boosts" type="java.lang.String" value="-.3F,.1F"/>
  </boostDocument>

Regards,
Jose García
