> +Question:+
> FIWARE - Orion LD offset parameter does not provide any results after threshold
> +Description:+
> I am using FIWARE Orion-LD in order to store Social Media posts, whose number exceeds 300,000.
> I would like to access all the entities of type SMPost which belong to a specific SMCollection.
> GET <orion_host>:1026/ngsi-ld/v1/entities?options=keyValues&q=belongsToCollection==%22urn:ngsi-ld:SMCollection:XX%22&type=SMPost&limit=1000&offset=XXX&options=count
> For this purpose, I am employing pagination, as instructed in the official documentation, using the parameters limit and offset. Using the parameter options=count, I confirm that indeed all the entities are correctly inserted in the MongoDB.
> Everything goes well until the offset is set to 34000, then, when exceeded, an empty list is returned, as a response.
> Is this a known issue?  Could you please provide an alternative way that I could get this data?
> Thank you very much in advance for your response.
