This is the web front of uDb, a project to make Larry Hatch database available again.
Supported operators are equal (=), not equal (!= or <>), below
(< or <=), above (> or >=). They can be combined
using AND (&) or OR (|) logical operators.
For example, year=1972&month=8|month=7&country=France will list cases that occurred on August of
1972, or in July of any year in France.
