I wrote a recommended plugin using the
WritingPluginExamle-0.9<http://wiki.apache.org/nutch/WritingPluginExample-0.9>.
To add the RecommendedQueryFilter to the list of filter that run by default
I added the below code in the plugin.xml
<!-- The RecommendedQueryFilter gets called when you perform a search. It
runs a
search for the user's query against the recommended fields. In
order to get
add this to the list of filters that gets run by default, you have
to use
"fields=DEFAULT". -->
<extension id="org.apache.nutch.parse.recommended.recommendedSearcher"
name="Recommended Search Query Filter"
point="org.apache.nutch.searcher.QueryFilter">
<implementation id="RecommendedQueryFilter"
class="org.apache.nutch.parse.recommended.RecommendedQueryFilter">
<parameter name="fields" value="DEFAULT"/>
</implementation>
</extension>
In the RecommendedQueryFilter.java I increased the boost value of the field
to higher number than the rest of the fields.
Inspite of this I could not see the results that have this field in the
first. I am not sure if it taking this field also for the default search
field.
I tried by writing the RecommendedQueryFilter.java extending the
RawFieldQueryFilter class and setting the boost value in the configuration
file. But this is not picking the boost value too.
So can anyone please help to an additional field along with the existing
default fields.
