You can type a single word or several words, for example:
a single word: asbestos
a phrase making a single subject: wood based boards
a combination of subjects: paint* nervous system
The more words you enter, the more selective your search will be:
ie the last example excludes items about paints unless the nervous system is also mentioned.
To widen your search, type OR between terms, eg:
solvent* OR paint* - finds any items where either solvent(s) or paint(s) are mentioned,
ie it includes water-based paints and engineering/cleaning solvents
You can use either capitals or lower case letters.
Asterisk * is a wildcard for different word endings. eg:
paint* - will find paint, paints, painter, painters, painting, painted, paintbrush, paintbox.
reproduc* - will find reproduction, reproductive, reproduce
The search program will try to put the most useful results first
Extra notes for information experts!
You can use the boolean search operators 'and', 'or', 'not' and () in searching, for example
stress and workplace
vdu or display screen
chemicals not formaldehyde
Without these booleans, swish will perform an 'and' search, for example
chemicals disease - is the same as
chemicals and disease
