Example Queries

VL Search Operators

AND operator

  • Description: The AND operator is implied when typing a search query with terms separated by spaces
  • Usage: Include "AND" between the search terms or just leave a space. Uppercase or lowercase does not matter.
  • Example: Searching for black cat in the search bar. The following queries are equivalent
black AND cat  
black and cat  
black + cat
  • Result: This query will return images that contains both the terms "black" AND "cat" in any order.

OR operator

  • Description: The OR operator is used to find results containing either one of the search terms or both
  • Usage: Include "OR" between the search terms. Uppercase or lowercase does not matter
  • Example: 
black cat OR black dog
black cat or black dog
  • Result: This query will return images containing either black cats, black dogs or both.

NOT operator

  • Description: The NOT operator is used to exclude terms from the search results
  • Usage: Prefix the term you wish to exclude with a minus sign (-)
  • Example: 
dog -black
  • Result: This query will return images with the term "black" in the metadata but will exclude any images that also contain the term "cat".

Exact match

  • Description: For an exact match of a phrase or sequence of words, use quotation marks
  • Usage: Enclose the exact phrase within double quotes
  • Example: 
"yellow flower"
  • Result: This query will return images where the metadata exactly matches the phrase "yellow flower" and not a more generic search which also returns other image which contain flowers or yellow objects

Combining operators

It is also possible to combine the operators above eg

flower -bird or tree and "red leave"
