How do I know which analyzer nutch is using during crawling/indexing?

[Roger Marin <rs...@gmail.com>]

Hello,

I implemented a plugin to change the default nutch analyzer to use the
snowball analyzer since I need stemming support, based on the french
analyzer.
When I search and the query gets parsed I can see the terms are getting
stemmed, however the search returns nothing, so I'm not sure what analyzer
nutch is using during indexing,
it doesn't seem to be picking up the analyzer from the plugin, is there a
way to get the analyzer nutch is using to index?

Thanks.

You should write your own QueryFilter that uses the same analyzer you
use for indexing and define it in your plugin.xml file.

<plugin>
   <extension id="...
              name="...
              point="org.apache.nutch.searcher.QueryFilter">
      <implementation id="YourQueryFilter"
                      class="your.package.name.YourQueryFilter">
      </implementation>
   </extension>
</plugin>
