Hi Bert,

SOLR in ODP? In the operation manual I don’t find nothing.

I'm not really sure what information is required here. Our Solr schema is
in the ckanext-ecportal extension [1], this contains the list of all fields
that are currently indexed (and how we have configured Solr to index them).
There is also some information  about the multilingual fields and the query
parser in the Operations Manual (p. 34). It seems like you would be the
best person to comment on the actual deployment aspects.

We don't have any special Solr query parsing in CKAN, we basically pass
your query straight through to Solr, so this information is best obtained
from the Solr documentation [2][3]. More information about our search API
parameters is given in the docs [4].

> In which fields we can do a search,

These are listed in our Solr schema [1].

We are not really using any stop words at the moment (the default
'protwords.txt' is used for English, but this is practically empty,
containing just two test examples).

Special characters will generally be stripped by our current Solr analyzers
at both index and query time, so currently you cannot search for these
characters.
