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.


Stone

DataStreams Against Resource Index?

 
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.
 
Regards
Steve
