Search bulk files locally

Pleiades nicely provides their bulk data (for locations, names, and places) in various formats, including .csv. We've created three functions pl_search_loc(), pl_search_names(), and pl_search_places() to search each of those datasets. As these are relatively large (approx 40K rows by 30 columns), dplyr is a nice approach to dealing with big-ish data. At this time dplyr is a dependency.

You can run pl_cache() first to get the raw data files from Pleiades

pl_cache()

Or, that function is run internally in pl_search*() functions for you.

Search across all tables in one database, or separately locations, names, or places. You can return the data (that is, a dplyr representation of the data) if you don't pass anything to the function call:

Gives each table in a list
