Helpful Search Tips:
Although your search may show hundred of matches, only the first 100 will be available. You may need to refine your search to find closer matches.
The following basic search operators may be useful for searching within DORY:
Put any phrase in double quotes to force an exact-match search. Use this to refine results for ambiguous searches, or to exclude synonyms when searching for single words.
Search for X or Y. This will return results related to X or Y, or both. Note: The pipe (|) operator can also be used in place of “OR.”
Search for X and Y. This will return only results related to both X and Y. Note: It doesn’t really make much difference for regular searches, as Google defaults to “AND” anyway. But it’s very useful when paired with other operators.
(This is a minus or dash) Exclude a term or phrase from the search.
Acts as a wildcard and will match any word or phrase.
Find pages with a certain word (or words) in the title.
Similar to “intitle,” but only results containing all of the specified words in the title tag will be returned.
Search for a range of numbers.
