Missing content (only titles) in Escher Tageblatt

[simon-clematide]

While checking on samples for the status of title in rebuilt:
These content items only have a title ("t" property) in rebuilt, but no full text. Seems to affect a lot more articles than the ones I sampled and looked at from these issues:

In the newly ingested data, there is also an important number of CI with content_length = 0 : 2,098,902.
With content_length = 1: 485,785 ( can be a glued word.)

These may correspond to incorrect page region segments, originating from bad OLR and/or errors in the conversion process.

We need to investigate further, also with comparing to the 'old' ingested data. I noticed that sometimes the title is equal to the full text (cannot count this in Solr, though.

The break down is available via this solr query and below.
