Complex search queries through the API

[bbucek]

Hello.

I wasn't sure where would be the best place to ask a question about the more complex API queries.
I find this resource very useful and but I'd like to explore the possibility of more complex queries than we have in this example:

api-training/archiveIt.py

Line 43 in 3aa088c

query = '/search?page=1&filter={"query":{"jsonmodel_type":"boolean_query","op":"AND","subqueries":[{"jsonmodel_type":"field_query","field":"primary_type","value":"digital_object","literal":true},{"jsonmodel_type":"field_query","field":"digital_object_id","value":"' + doid + '","literal":true}]}}'

for example:
is it possible to extend the subqueries further down and filter results combining AND and OR operators to pull the results from the Archive?

Thanks for your help.
