Subject RE: Searching Binary Nodes

Thanks for that Marcel seems to be working fine. 

I know this might sound like an odd question but the spec mentions 'text
searching' how is this different from just searching a property with a
String value. I guess I'm wondering why there is a like function as well
as a contains function ?

This depends on how the text filter extracts the text and assigns it to
index fields. E.g. the TextPlainTextFilter adds a fulltext field to the
node that gets indexed. This means the binary content can only be
searched with the jcr:contains() function. I assume the same applies to
the Word filter you are refering to.
