Subject [jira] Commented: (JCR-1079) Extend the IndexingConfiguration to allow configuration of reuseable analyzers
Date Fri, 31 Aug 2007 13:14:30 GMT

    [ https://issues.apache.org/jira/browse/JCR-1079?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12524079
] 

Marcel Reutegger commented on JCR-1079:
---------------------------------------

The DTD is indeed the only file we have. There is no example, except for the wiki page here:
http://wiki.apache.org/jackrabbit/IndexingConfiguration

For testing you can create a new workspace under jackrabbit-core/applications/test/workspaces.
We already have two workspaces, which are used for the JCR tests. Just create a folder, put
a workspace.xml and an indexing_configuration.xml in there. You also might have to adapt the
build script, otherwise it probably remove the files again when you call: mvn clean.

> To the indexing_configuration.xml a xml block of analyzers should be configurable. In
each <index-rule> to a property an analyzer can be assigned. This means, that property
will be analyzed with that specific analyzer. In the first place, it enables multilingual
indexing. 
> Documentation needs to be added explaining the difference in searching in the node scope
[jcr:contains(.,'foo')] and in some property [jcr:contains(@myprop,'foo')]. The node scope
will always be searched and indexed with the default analyzer, which can be configured in
the workspace.xml in  the  <SearchIndex> element.
> Below a possible indexing_configuration.xml snippet is shown. Also node the possible
enhancement (not sure wether this implementation will have it, because it requires a lot of
filter Factories and is probably out of scope). Adding custom filters which do not need a
factory might be easier.
> <analyzers>
> 	<analyzer name="fr" class="org.apache.lucene.analysis.fr.FrenchAnalyzer"/>

maxGram="2"/>
