Using Search Filters
The Truveo video search service supports several filters that can be included in your search query to further refine your
search results. These filters can be used, for example, to narrow your search results to include only videos that have
a specified duration or bitrate, are hosted on a specific site, or are a specified number of days old.
Please note that
filters can only be applied when submitted in conjunction with one or more search keywords. A filter submitted without
any search keywords will return no results. For example, the query 'runtime:>5' will return no results, while the query
'elvis runtime:>5' will return all videos about elvis that are longer than 5 minutes. A complete listing of the available
search filters and their usage is shown below.
type:
The type: filter can be used to restrict video results based on the model by which a user can access a given video.
For example,
type:free |
Finds all videos that can be viewed for free and do not require user registration. |
type:reg |
Finds all videos that can be viewed for free but require user registration. |
type:sub |
Finds all videos that can only be viewed with a user subscription. |
type:rent |
Finds all videos that can be rented for a fee. |
type:buy |
Finds all videos that can be purchased for a fee. |
runtime:
The runtime: filter can be used to find videos of a specified duration or runtime, as measured in minutes. For example,
runtime:>10 |
Finds all video records with a runtime longer than 10 minutes. |
runtime:<1 |
Finds all video records with a runtime shorter than 1 minute. |
runtime:5 |
Finds all video records with a runtime of 5 minutes. |
quality:
The quality: filter can be used to find videos that meet a certain quality threshold. The quality: filter relies on
a variety of approaches to determine video quality. In addition to relying on bitrate, the quality filter may also
take into account the resolution, runtime, framerate, height and width of the video in order to estimate quality.
The quality filter can be used as follows:
quality:poor |
Finds all records for videos that are
poor quality or better. |
quality:fair |
Finds all records for videos that are
fair quality or better. |
quality:good |
Finds all records for videos that are
good quality or better. |
quality:excellent |
Find all records for videos that
are excellent quality or better. |
bitrate:
The bitrate: filter can be used to find videos with a specific bitrate, as measured in Kbps. For example,
bitrate:>700 |
Finds all video records with a bitrate of 700Kbps or higher. |
bitrate:<100 |
Finds all video records with a bitrate of 100Kbps or lower. |
bitrate:300 |
Finds all video records with a bitrate of 300Kbps. |
format:
The format: filter can be used to find videos of a specific format. For example,
format:win |
Finds all records for videos in a format suitable for Microsoft Windows Media Player. |
format:real |
Finds all records for videos in a format suitable for Real Media Player. |
format:qt |
Finds all records for videos in a format suitable for Apple QuickTime Media Player. |
format:flash |
Finds all records for videos in a format suitable for Adobe Flash Player. |
format:hi-q |
Finds all records for videos in AOL Hi-Q video format. |
site:
The site: filter can be used to find videos located on a specific web domain. For example,
site:video.msn.com |
Finds all records for videos located on the video.msn.com website. |
site:yahoo.com |
Finds all records for videos located anywhere on the yahoo.com website. |
days_old:
The days_old: filter can be used to find videos indexed within a specified time period. For example,
days_old:<2 |
Finds all video records that were indexed within the past two days. |
days_old:>30 |
Finds all video records that were indexed at least 30 days ago. |
days_old:5 |
Finds all video records that were indexed five days ago. |
days_old:>7 days_old:<14 |
Finds all video records that were indexed at least seven but not longer than 14 days ago. |
file_size:
The file_size: filter can be used to find videos with a specified file size, as measured in Mbytes. For example,
file_size:<2 |
Finds all video records for files that are less than 2 Mbytes in size. |
file_size:>10 |
Finds all video records for files that are greater than 10 Mbytes in size. |
file_size:1 |
Finds all video records for files that are 1 Mbyte in size. |
