Hi Steve, Thanks for the information. I played with gSearch a little bit and looks like it has some limitation. For example, I can issue the Lucene search expression
dsm.rss:"podcast" to search the "rss" data stream for "podcast" since each data stream will be indexed as a Lucene field. But what if I want to search across all the data streams without explicitly listing all the data streams? dsm.ds1:"podcast" dsm.ds2:"podcast" ... is really awkward. Does gSearch accept a simple dsm.*:"podcast" expression to search ALL data streams? Thanks.

Hi Stone Theoretically you can do this - but you would need to add the content in RELS-EXT or RELS-INT, for example <info:fedora/myns:somepid/DS1> <hasDatastreamContent> "literal content of datastream" However it would probably be more appropriate to use search/indexing tools designed for this - for example Fedora GSearch/SOLR.
