Please find attached something I wrote today. It has not been yet tested extensively, and the documentation could be improved, but I thought it would be good to get comments sooner rather than later.
Would folks find this useful?
Yes, very useful, especially if you added one additional feature that looks straightforward from the code below. That is a facility to append the stored fields from the non-storedFieldReaders to the Document on-demand. This would solve a problem that has hit me several times, and that others on the list seemed to have encountered as well. If a document contains a bunch of small stored meta-data fields that are used for categorization purposes, and one or a few large stored ontent fields, then it can be important to be able to scan a large number of results quickly for purposes of analyzing the categorical fields. This is currently slowed down by the unnecessary loading of the content field(s). The ability to ignore the stored fields in certain readers below solves this, but I didn't see a way to access those fields when they are needed (e.g.., for highlighting or browsing a result -- something done on much fewer of the results).
Should it go into the core or in contrib?
Seems worth of the core to me.
Very cool,
Chuck
