Broadening the Search
If the results you get from either a simple or compound search are too narrow, Cumulus can be of assistance again. The search method Find and Add to Current Collection adds the results of a subsequent search to the records contained in the current collection.
This search method can be seen as an or Boolean operator. That is, after your first search, you conduct another search using a different criteria, and the final results are the same as from the corresponding compound search using or.
