Read multiple collections from the same data source

[doublebyte1]

Currently, the Portugal CRUS layer is split into multiple files:

Original layer:
https://snig.dgterritorio.gov.pt/rndg/srv/por/catalog.search#/metadata/517c5023-04cc-47a4-99f7-bb32814dd62f

Multiple layers:
https://snig.dgterritorio.gov.pt/rndg/srv/por/catalog.search#/search?resultType=details&sortBy=referenceDateOrd&from=1&to=20&fast=index&_content_type=json&type=dataset%2Bor%2Bseries&anysnig=CRUS

Can we filter the original layer, to obtain the multiple collections? Is that efficient?

Some ideas to investigate:

• create postgres views for the original table, for instance using keywords
• create the filter directly on the OGC API Features request (e.g.: using CQL or q)
