Place quotes around a phrase

Use the * for truncation
When you put an asterisk at the end of a search term it searches for words with any possible ending.
Limit search to particular types of documents by using
site:gov = documents produced/authored by the government at all levels (federal,state,local) and government-sponsored research
This would be especially useful for the Policy Snapshot:
"You will review what is happening on the ground related to your policy issue by investigating the current practices in one state. You will research a snapshot of how federal, state, and local policies play out in that state to understand your issue both in its current and historic form"
site:edu = documents produced/ authored/ sponsored by educational entities
