Subject [jira] Commented: (JCR-415) Enhance indexing of binary content
Date Mon, 18 Dec 2006 15:45:24 GMT
    [ http://issues.apache.org/jira/browse/JCR-415?page=comments#action_12459384 ] 
Marcel Reutegger commented on JCR-415:

I would like to get this change into the next major release (1.3) and propose the following

- Create a new module jackrabbit-text-extractors which will initially contain the jackrabbit-extractor
patch provided by Jukka
- Migrate the jackrabbit-text-filters into the new extractors module
- Add jackrabbit-text-filters as dependency to jackrabbit-core
- Remove the jackrabbit-text-filters module and do not create releases anymore for this module.
Jackrabbit would still support existing releases of jackrabbit-text-filters but the interface
TextFilter will be deprecated (see Jukkas' patch) and developers are encouraged to use the
new TextExtractor interface.

Does this make sense?

> Indexing of binary content should be enhanced in order to allow either configuration
what fields are indexed or provide better support for custom NodeIndexer implementations.
> The current design has a couple of flaws that should be addressed at the same time:
> - Reader instances are requested from the text filters even though the reader might never
be used
> - only jcr:data properties of nt:resource nodes are fulltext indexed
> - It is up to the text filter implementation to decide the lucene field name for the
text representation, responsibility should be moved to the NodeIndexer. A text filter should
only provide a Reader instance.
> With those changes a custom NodeIndexer can then decide if a binary property has one
or more representations in the index.
