Thanks. I'm starting to get a better idea of the whole picture ;)
Could you also share the query you are running? do run the cross_field
query against the default field or the 'raw' field?

To me this means that the documents that are indexed in solr and
Es are
different. Is this correct?
they are identical, but in the newer elasticsearch version the
edgengrams and the raw tokens are stored in separate field, which
allows boosting entire words. we are using the fields
<https://github.com/christophlingg/photon/blob/komoot/es_config/mappings.json#L47> feature
for that.
Would you mind sharing the schema of the document you are indexing in
Solr and ES ? We may be able to provide tips / ideas to improve
search
performance
sure!
