[opencms-dev] Lucene and Binary Documents

[Ben Rometsch]

Hi Matt,

Thanks for the reply. If I just want to get the document title to be
included in the Lucene index, looking at the code in the
net.grcomputing.opencms.search.BodylessDocument class it appears to ignore
what the CMSObject is, and attempt to index it regardless. Is this correct?

If this is the case, is it simply a matter of instructing Lucene to index
obects other than HTML files in the VFS  (i.e. Documents) ? Or would I have
to create another class, something like
net.grcomputing.opencms.search.FileDocument and add a new hook into that
class via the registry.xml fragment?  Or does the BodyLess document provide
this functionality, and it's just a matter of adding a new XML fragment to
the registry.xml are?

Sorry for all the questions!

Ben

I've not done this with the Lucene module, yet. Someone on the list last
month said they had done something like this running lucene over and
_exported_ version of the files. The Lucene module, however, operates inside
OpenCMS directly on the VFS.

The Lucene module indexes certain properties for binary files. If you give
each document a title, for instance, then it can be indexed pretty easily.
If you have the source code, you can look at
net.grcomputing.opencms.search.BodylessDocument for an idea as to how binary
indexing works.
