keyword searching

[antje-s]

In the keyword search it is apparently possible to search for several keyword values, whereby the default operator ‘AND’ seems to be used, e.g.

1. prediction
   https://wis2.dwd.de/gdc/collections/wis2-discovery-metadata/items?f=json&limit=200&keywords=prediction
   --> numberMatched = 58
2. prediction,global
   https://wis2.dwd.de/gdc/collections/wis2-discovery-metadata/items?f=json&limit=200&keywords=prediction,global
   --> numberMatched = 34
3. prediction,global,"Weather and Climate"
   https://wis2.dwd.de/gdc/collections/wis2-discovery-metadata/items?f=json&limit=200&keywords=prediction,global,%22Weather%20and%20Climate%22
   --> numberMatched = 29

It seems to be possible to change the operator to OR, e.g. via
https://wis2.dwd.de/gdc/collections/wis2-discovery-metadata/items?f=json&limit=200&q=(keywords:prediction%20global)
--> numberMatched = 96

Does this behaviour apply in principle?

Similar to #25, for single term equality queries, I would suggest a "safer" way to query with:

https://wis2.dwd.de/gdc/collections/wis2-discovery-metadata/items?f=json&limit=200&keywords=prediction%20global

For compound queries with specific syntaxes such as AND OR NOT, etc., I would delegate to your examples of q per above. These examples are also in the WIS2 Cookbook (please feel free to suggest more examples there as well).
