Extend the IndexingConfiguration to allow configuration of reuseable analyzers
------------------------------------------------------------------------------
Key: JCR-1079
URL: https://issues.apache.org/jira/browse/JCR-1079
Project: Jackrabbit
Issue Type: New Feature
Affects Versions: 1.3.1
Reporter: Ard Schrijvers
Priority: Minor
Fix For: 1.4
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"/>
<analyzer name="de"
class="org.apache.lucene.analysis.de.GermanAnalyzer"/>
<analyzer name="compound"
class="org.apache.lucene.analysis.SimpleAnalyzer">
<filter class="jr.StopFilterFactory" words="stopwords.txt"/>
<filter class="jr.EdgeNGramTokenizerFactory" side="front"
minGram="1" maxGram="2"/>
</analyzer>
</analyzers>
<index-rule nodeType="nt:unstructured">
<property analyzer="fr">bode_fr</property>
<property analyzer="de">bode_de</property>
</index-rule>
