Subject RE: Searching for binary values
Date Mon, 30 Aug 2010 07:50:06 GMT

Bloody hotmail, screwed my awesome formatting ;)Hope it's ok now.

here comes the addBinaryValue method body:...//standard way of indexingString jcrData = mappings.getPrefix(Name.NS_JCR_URI)
+ ":data";if (jcrData.equals(fieldName)) {	InternalValue type = getValue(NameConstants.JCR_MIMETYPE);
if (type != null) {	    Metadata metadata = new Metadata();	    metadata.set(Metadata.CONTENT_TYPE,
type.getString());	    // jcr:encoding is not mandatory	    InternalValue encoding = getValue(NameConstants.JCR_ENCODING);
    if (encoding != null) {		metadata.set(Metadata.CONTENT_ENCODING,		encoding.getString());
    }	    doc.add(createFulltextField(internalValue, metadata));	}} else {	//everything
else gets indexed as well	MimeTypes gk = new MimeTypes();	MimeType mimeType = gk.getMimeType(internalValue.getStream());  
   	Metadata metadata = new Metadata();	metadata.set(Metadata.CONTENT_TYPE, mimeType.getName());
doc.add(createFulltextField(internalValue, metadata));}...

and here we have my custom parser (and I can see it's being started everytime the binary value
with my custom mime type is added):XHTMLContentHandler xhtml = new XHTMLContentHandler(handler,
metadata);xhtml.startDocument();...fetch keywords...for(String value: keywords) {	xhtml.characters(value);
xhtml.characters(" ");}xhtml.endDocument();...

>>>>>> I'm looking for a clarification how the query is processed in my
customized jackrabbit instance. In my case the NodeIndexer is subclassed so it can add the
binary value to the indexed Document even if it does not have nt:resource type. Then Tika
has been customized with my mimetype so the parser is able to recognize the binary stream
through it's magic and of course the tika's Parser object was implemented to support the custom
binary stream to extract words from it.If I run a query on nt:resource nodes it correctly
returns files including the searched word as expected but when I invoke a similar query on
a binary property (and the content of this binary property is exactly the type of the stream
Tika can parse) it does not return anything - is there a way out?
