If I perform such a query I still get 0 hits...
Here's my plugin.xml files:
------------------ Indexing plugin -----------------------
<?xml version="1.0" encoding="UTF-8"?>
<plugin
id="index-quiew"
name="Quiew Indexing Filter"
version="1.0.0"
provider-name="nutch.org">
<extension-point
id="org.apache.nutch.indexer.IndexingFilter"
name="Nutch Indexing Filter"/>
<runtime>
<library name="index-quiew.jar">
<export name="*"/>
</library>
</runtime>
<extension id="org.apache.nutch.indexer.quiew"
name="Nutch Quiew Indexing Filter"
point="org.apache.nutch.indexer.IndexingFilter">
<implementation id="QuiewIndexingFilter"
class="org.apache.nutch.indexer.quiew.QuiewIndexingFilter"/>
</extension>
</plugin>
---------------- Query plugin ----------------------
<?xml version="1.0" encoding="UTF-8"?>
<plugin
id="query-quiew"
name="Quiew Query Filter"
version="1.0.0"
provider-name="nutch.org">
<extension-point
id="org.apache.nutch.searcher.QueryFilter"
name="Nutch Query Filter"/>
<runtime>
<library name="query-quiew.jar">
<export name="*"/>
</library>
</runtime>
<extension id="org.apache.nutch.searcher.quiew.QuiewQueryFilter"
name="Nutch URL Query Filter"
point="org.apache.nutch.searcher.QueryFilter">
<implementation id="URLQueryFilter"
class="
org.apache.nutch.searcher.quiew.QuiewQueryFilter"
fields="url"/>
</extension>
</plugin>
Clearly I enabled the plugins in the nutch-site.xml file... :-)
Thanks for your replies!
