Do you want to search for specific years or an exact date?
Use the special date box. It's the bottom line of the search form.

Did you find years anyway? They just happened to be somewhere in the text.
When you use the special date box: delete any years from the original question.

All words in a search box are considered to be a single term. But:
Raid on the Medway 1 term.
World War Two bombardment 2 terms.

Which words are a single term? Please show us.
Use separate search boxes, so we will know what to search:
World War Two
bombardment


Still, we give it a try. We will combine and correct.
We will look where these terms occur together, but not necessarily adjacent.
These results are displayed as follows:
"World War Two" + bombardment

They will almost always be satisfactory.
The words in quotes (") are adjacent.
The words after a plus sign (+) occur somewhere else.
