-------------------------------------
> That's OK with me, but I think being able to configure an analyzer in an
> index rule also seems useful to me.
That is fine with me, but we do have to realize, that I cannot make a
distinction between setting it for a property in a single "index-rule" or
setting it global like I did describe it. It is because when analyzing or when
parsing some query for a field, all I know in the analyzer is the the string
representation (JCR-style name) of the given property.
If that is fine with you I will add this configuration option and write
documentation about it.

> 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.
