* and ?)* matches zero or more characters. ? matches exactly one character.
Example: te*st matches "test", "teest", and "tempest". 199? matches "1990" through "1999".
OR, -)Combine multiple terms. A space between words implies AND.
Example: apple banana finds records with both. apple OR pear finds records with either. apple -pie finds records with "apple" but not "pie".
"...")Enclosing words in double quotes searches for that exact sequence.
Example: "quick brown fox" will only match that exact phrase.
