downloads.DownloadQuery

The DownloadQuery type of the downloads API defines a set of parameters that can be used to search the downloads manager for a specific set of downloads.

This type is used for example in downloads.search() and downloads.erase(), as a query object to filter the set of DownloadItems to return or erase.

Values of this type are objects. They contain the following properties:

queryOptional

An array of strings. Include only DownloadItems whose filename or url contains all of the given strings. You can also include terms beginning with a dash (-) — these terms must not be contained in the item's filename or url for it to be included.

startedBeforeOptional

A DownloadTime. Include only DownloadItems that started before the given time.

startedAfterOptional

A DownloadTime. Include only DownloadItems that started after the given time.

endedBeforeOptional

A DownloadTime. Include only DownloadItems that ended before the given time.

endedAfterOptional

A DownloadTime. Include only DownloadItems that ended after the given time.

totalBytesGreaterOptional

A number representing a number of bytes. Include only DownloadItems whose totalBytes is greater than the given number.

totalBytesLessOptional

A number representing a number of bytes. Include only DownloadItems whose totalBytes is less than the given number.

filenameRegexOptional

A string representing a regular expression. Include only DownloadItems whose filename value matches the given regular expression.

urlRegexOptional

A string representing a regular expression. Include only DownloadItems whose url value matches the given regular expression.

limitOptional

An integer representing a number of results. Include only the specified number of DownloadItems.

orderByOptional

An array of strings representing DownloadItem properties the search results should be sorted by.

To specify sorting by a property in descending order, prefix it with a hyphen, for example -startTime.
