Each Entity has the root API that can be used to retrieve a list of entity records belonging to the entity. The following are fundamentals query string parameters you can use to search a filter data:
Search string to filter records by using RSQL query. Example:
search=name==Andrea and age>=20
limit the result of the query
comma separated strings to order result by entity fields
if you order and limit query result you could want to perform multiple request to retrieve different data. start can be used as the offset for the already queries data
OpenAPI documentation already provide the previous parameters for each resource. So the better way to understand how them works is to try.
