I have run into a design problem with ISearchable. I have developed a control that displays news items. I want the contents of the news items to be searchable, and thus need to implement ISearchable.  

Design problem: 
ISearchable is supposed to return a collection of SearchItemInfo instances. Typically the size of the Content field in any one of these instances is 16-32 kbyte. I have several tens of thousands news item to be indexed, which means I need to instantiate several megabytes of SearchItemInfo instances in order to create the collection. This operation also take a lot of time, which effectively freezes DNN when started by the scheduler.

If ISearchable would have been implemented with an iterator instead, the problem wouldn't exist. My code would happily create single SearchItemInfo instances on demand, with no heavy memory and cpu usage.

I am not sure how to proceed with this issue, obviously I need to solve the problem somehow, question is how.

Any feedback on this would be greatly appreciated!
