Tips boolean expressions (expert's search)
- Use boolean expressions only if you are a experienced user of such logical expressions. Generally it should be sufficient to use the "matching all words" or "matching some words" modes.
- Use logical operators '&' (AND), '|' (OR), '~' (NOT) as well as brackets '()' for grouping.
- Searching for phrases and quotations is not explicitly possible. Use the standard setting "matching all words". (Note that there is a difference to search for phrases as you don't search for your search words as concatenated string.
- Search is case insensitive.
- Example: '(energy & technology) | ~kyoto'
