• Search terms can also contain the * wildcard as in the following example:
  climat*

• Search phrases are entered without any syntax like in the following example:
  dealing with natural hazards

• Exclude terms with the not operator, as in the following example:
  organic food not gmo

• Require compulsory terms with the binary inclusion operator, and, as in the following example:
  organic food and gmo
  This example requires both the term organic food and gmo to be present.
