how to search images (*.jpg, *.png)

Hello,

How can I search images in the JR repository? I put this exrtractor:
org.apache.jackrabbit.extractor.PngTextExtractor and uploaded a .png  & .jpg
file and try search using this query:

"/jcr:root/photo/upload/username//element(*,nt:base)[fn:lower-case(@type)='jpg']"

i do not get any hits. any idea.

Thanks a lot.
Cheers.

Hi,

if you are just looking for all jpg and png images then the following
will do the trick:

//element(*, nt:resource)[@jcr:mimeType = 'image/jpg' or @jcr:mimeType
= 'image/png']

assuming you store the images as nt:file/nt:resource nodes.

a text extractor is not needed for this.

regards
 marcel
