Help: Boolean, proximity and truncation searching
To narrow the scope of your search you can use the following special sets of predefined words, called operators, to join together your search terms:
C19 Index allows you to combine your search terms so you can target your search at more specific areas. For example, from the Search page you can list records in C19 Index which contain the words employment and children.
You combine your search terms using the following special keywords, called Boolean operators:
e.g. employment AND children
If you have entered search terms in more than one search box, C19 Index treats them as if they were combined using the AND operator.
Note that if you want to search for the word 'and' in a phrase, such as 'food and drink', you should type the phrase into the search box and enclose it in double quotes; for example, "food and drink".
e.g. Army OR Navy
If you select more than one search term from a list, C19 Index automatically combines them in the search box using this operator.
e.g. emigration NOT Ireland
Proximity operatorsC19 Index not only allows you to search for a particular word or phrase, but also enables you to refine your searches by using two proximity operators to look for words that are close to each other:
e.g. treaty NEAR Netherlands
e.g. domestic FBY servants
C19 Index allows you to list documents containing variations on a search term by using the * (asterisk) or ? (question mark) wildcard characters.
Use an asterisk to find variations on a word ending.
e.g. work* finds work, works, working, worker, workman, workmen
Use a question mark in the place of a letter to find variations in spelling.
e.g. wom?n finds woman and women.
Note that you can only use the ? wildcard in the middle of a word.
If you are performing a phrase search, you can only use wildcard operators in the final word in the phrase.
