*Search hints for Location and Collector Name fields:

• use + (plus sign) before words to include all words in your search results (equivalent to the AND boolean operator): +black +canyon
• use " " (double quotes) to search for an exact phrase: "Rocky Mountain National Park"
• use - (minus sign) before words to exclude words from your search results (equivalent to the NOT boolean operator): -boulder +mountain +park
• use of no symbols will retrieve records with at least one of the search terms (equivalent to the OR boolean operator)
• keep search more general to capture all desired records; e.g., a search on 'Ramaley' will return records that contain 'Francis Ramaley' and 'F. Ramaley'; a search on '+Verde +Park' will return 'Mesa Verde National Park' and 'Mesa Verde Nat. Park'.
