- Check if your spelling is correct, or try removing filters.
- Your search terms must be less than or equal to 255 characters.
- Use of quotation marks:
- Use quotation marks around a phrase or concept of two or more words to ensure that the exact phrase or concept is searched for as a whole and not picked apart by the search engine.
- Remove quotation marks around a phrase or concept to match each word individually. For example "blue drop" will match less than blue drop.
- Separate your keywords with Boolean search operators OR, NOT, AND. Note: Boolean operators must be ALL CAPS. For example:
- ocean OR river will broaden search results and retrieve records that contain the word ocean or river
- ocean NOT Atlantic will narrow search results and retrieve records that contain the word ocean, but will exclude anything containing Atlantic
- ocean AND river will narrow search results and return records that contain both ocean and river.
