Subject [jira] Commented: (JCR-1079) Extend the IndexingConfiguration to allow configuration of reuseable analyzers

Ard Schrijvers commented on JCR-1079:
-------------------------------------

I have implemented the first part, without enabling configuration of an analyzer in a index
rule (because of the implication that it ends up being global, though if wanted, can add it.
Let me know). Current configuration looks for example like:

<analyzers> 
        <analyzer class="org.apache.lucene.analysis.fr.FrenchAnalyzer">
            <property>test:fr_mytext</property>
            <property>test:fr_body</property>
        </analyzer>
        <analyzer class="org.apache.lucene.analysis.de.GermanAnalyzer">
            <property>test:de_mytext</property>
            <property>test:de_body</property>
        </analyzer>
        <analyzer class="org.apache.lucene.analysis.nl.DutchAnalyzer">
            <property>test:nl_mytext</property>
            <property>test:nl_body</property>
        </analyzer>
</analyzers>

Now, I want to add some tests showing the possible confusing difference in search results
between a property and a node scope search. The only problem is that untill now, I do not
see a indexing_configuration.xml in the jackrabbit trunk.  I do see a indexing-configuration-1.0.dtd
only.

Is it possible add some tests with respect to some indexing_configuration.xml? It might be
a problem that the indexing_configuration.xml holds for all the tests regarding the workspace
then, or not? Has anybody an idea how to add some tests for the indexing_configuration.xml?

> 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>
