Add Search Filters With OR
You can use the OR option to include several different options
in one search by appending keywords to a normal AND query. Useful when
you want to narrow down a broad category into a sub-genre that can be defined
by a few representative keywords.
A couple of example OR searches are shown below:
- Sparrows. You may
wish to search for information on sparrows, but just the Harris, Le Conte, or
Savannah sparrows. In the following example, the OR clause is joined
to the rest of the query by an AND clause,
so at least one of the sparrow types listed must be included on any page returned.
bird
AND sparrow AND (harris OR conte OR savannah)
- Romantic painting. You may wish to get more information on the romantic
painting period, but particularly on the painters Corot, Delacroix, or
Géricault.
You can narrow down your search to those three with the following query:
"romantic
painting" AND (corot OR delacroix OR gericault)
