Question about SearchIndex

[Ducrocq Christophe]

Hi,

 

I have a question about tag SearchIndex in a repository configuration
file (repository.xml).

 

I put in the file a configuration by default in tag SearchIndex : 

 

<?xml version="1.0"?>

<Repository>

....

<PersistenceManager
class="org.apache.jackrabbit.core.state.obj.ObjectPersistenceManager" />

        <SearchIndex
class="org.apache.jackrabbit.core.query.lucene.SearchIndex">

            <param name="path" value="${wsp.home}/index"/>

            <param name="useCompoundFile" value="true"/>

            <param name="minMergeDocs" value="100"/>

            <param name="volatileIdleTime" value="3"/>

            <param name="maxMergeDocs" value="100000"/>

            <param name="mergeFactor" value="10"/>

            <param name="bufferSize" value="10"/>

            <param name="cacheSize" value="1000"/>

            <param name="forceConsistencyCheck" value="false"/>

            <param name="autoRepair" value="true"/>

            <param name="analyzer"
value="org.apache.lucene.analysis.standard.StandardAnalyzer"/>

            <param name="queryClass"
value="org.apache.jackrabbit.core.query.QueryImpl"/>

            <param name="idleTime" value="-1"/>

        </SearchIndex>

 

...

</Repository>

 

But, I will want to understand the role of each parameter to optimize
the configuration of my repository.

A person can it explain me?

 

 

 

A last question, which are the various possibilities for the attribute
"class"?

 

 

Tank you for your help.

 

Kind Regards,

 

Christophe
