The server accepts a list of tag categories for inclusion and
exclusion. The categories in the include list imply to return items
that have at least one tag of each category. The categories in the
exclude list imply to return all items that have no tag in any of
these categories.
- Use another external tool to convert pdf to pdf which also adds the
extracted text as another layer into the pdf
- Although not used, the external conversion routine will now check
for an existing text file that is named as the pdf file with extension
`.txt`. If present it is included in the conversion result and will be
used as the extracted text.
- text extraction for pdf files happens now on the converted file,
because it may already contain the text from the conversion step and
thus avoids running OCR twice.
- All errors during conversion are not fatal; processing continues
without a converted file.
A request to cancel a job was not processed correctly. The cancelling
routine of a task must run, regardless of the (non-final) state. Now
it works like this: if a job is currently running, it is interrupted
and its cancel routine is invoked. It then enters "cancelled" state.
If it is stuck, it is loaded and only its cancel routine is run. If it
is in a final state or waiting, it is removed from the queue.
The task runs on application start. It sets the schema using solr's
schema api and then indexes all data in the database. Each step is
memorized so that it is not executed again on subsequent starts.
This is a more expensive query, since the tags must be resolved per
item. This is now implemented by doing additional queries while
caching each resolved tag.
