Several productTypes in one request

[chadelmas]

It would be useful to be able to query multiple product types in a single request (search or download).

For now, I use the same criteria (except the product type) twice, to request SWOT products with provider hydroweb_next for each processing.

Example :
What I do now (on an example)

dag = eodag.EODataAccessGateway()
dag.set_preferred_provider("hydroweb_next")
search_criteria = {
    "productType": "SWOT_L2_HR_RIVERSP_REACH",
    "start": "2024-01-01",
    "end": "2024-10-31",
    "geom": {
        "lonmin": bbox[0],
        "latmin": bbox[1],
        "lonmax": bbox[2],
        "latmax": bbox[3],
    },
}
results_reach = dag.search(**search_criteria)
search_criteria["productType"] = "SWOT_L2_HR_RIVERSP_NODE"
results_node = dag.search(**search_criteria)

What it could be :

dag = eodag.EODataAccessGateway()
dag.set_preferred_provider("hydroweb_next")
search_criteria = {
    "productType": ["SWOT_L2_HR_RIVERSP_REACH", "SWOT_L2_HR_RIVERSP_NODE"],
    "start": "2024-01-01",
    "end": "2024-10-31",
    "geom": {
        "lonmin": bbox[0],
        "latmin": bbox[1],
        "lonmax": bbox[2],
        "latmax": bbox[3],
    },
}
results = dag.search(**search_criteria)

Thanks for the suggestion @chadelmas. The tricky part of this feature would be to handle pagination and sort properly for providers that do not support cross-collections search natively
