If you pass a structure as the last argument to your dynamic finder/counter call, we will consider that by convention to be your query options.
The valid query options are:
ignorecase : Ignores the case of sort order when you set it to true.
maxResults : Specifies the maximum number of objects to be retrieved.
offset : Specifies the start index of the resultset from where it has to start the retrieval.
cacheable : Whether the result of this query is to be cached in the secondary cache. Default is false.
cachename : Name of the cache in secondary cache.
timeout : Specifies the timeout value (in seconds) for the query
datasource : The datasource to use, it defaults to the application
sortBy : The HQL to sort the query by
autoCast : No more casting, let us do auto casting for you
asStream : Want a stream back instead of the results, no problem!
