I was having trouble with spotlight not showing finding PDFs in the DT database. Some documents it would find, but not all. I tried recreating and rebuilding the DT spotlight index and recreating all the indices on my HD via mdutil. Neither helped. It seemed that documents I had manually scanned were fine, however documents dragged into the database from finder were not picked up in spotlight. I narrowed it down to those documents with a populated URL field. If I empty the field spotlight finds them again.
I thought maybe just touching the document did something, so I tried adding annotations and resaving but that didn’t help.
As a final proof I put some text back into the URL field and again spotlight would not find the document. Remove it, and bingo, it’s back.
Anyone else experienced this? Is it a bug or do I have something misconfigured somewhere?
