Our documentation on Advanced Searching, particularly in the Operators Reference - WAS section needs to be updated, since there is a syntax error specified when using the DURING keyword, whereby:

• There must be a bracket to hold the values of start and end date when using the DURING keyword
• The date specified is not in correct format. The format should be "yyyy/mm/dd"

The syntax example stated in our docs:

status WAS "Resolved" BY jsmith DURING "01/01/2010","01/01/2011"

The correct syntax is:

status WAS "Resolved" BY jsmith DURING ("2010/01/01","2011/01/01")

See the example screenshot below:

• syntax specified in our docs
