to broaden, add more items to an extant dataset

to narrow, query with a dataset's items

The basic idea here is that we want to simply add to or narrow search results. The users probably should not realize that a dataset is being used, if that's the approach we use. Perhaps we need to add a dataset field to the advanced query, then when the user adds or narrows, we can silently populate that field on the advanced query form, and another field that is either "narrow" or "broaden" to either only search within that dataset or to add all plots in that dataset to the results.

this should be doable, and is very useful functionality.

this could be done by 1.2

The first step of this is just to allow users to search within a dataset, which could be the datacart to find stuff within some group of plots that they were initially interested in. Logging in and creating a new datacart should resolve circular issues as far as the datacart is concerned. (that is, you can't add the subset to the datacart if you searched within the datacart.)

Negative searched may also be desired, and soem functionality to merge, intersect, remove from datasets (standard ven diagram stuff) may be implemented to do this.
