Template caching and template search issue

[squishi]

I have made a change to the "postbit_attachmentthumbnail" template.
In there, I added a parameter to the URL of the attachment.
This is working for attachments that are not embedded.
For embedded attachments, the url parameter does not show.

So I reprocessed the post cache. Still, the parameter does not show.

Is there another template cache that I am not aware of?

I can see that I modified the correct template. It is the only one that contains the phrase "image_larger_version_x_y_z".

There is however another obscurity on my board.
When I search for the string "image_larger_version_x_y_z", the first few styles will not show that template in teh results.
When I search for the template name, the first few styles will show the template.

That's strange, and I think there could be a connection to the above issue?

I have already re-built the styles a few times. That did not help either.
