Understanding Search Types
When you add a term to the header, the Search app associates the entry with a search type that partially determines how your search is executed. Metadata is the default search type for every new search term, but multiple other search types exist — each with their own icon. For example in the following illustration, the user has created a new phonetic search with a value of “London”. You know that this is a phonetic search because of the icon at the left-side of the term.
The following table describes the different Search Type options.

Description |
|
Any |
When you select this search type, MediaCentral Cloud UX looks for your search term across all text-based Metadata fields, including those defined in the Dates and Markers & Segments categories. The Any search type does not return matches against Phonetic metadata. n Avid recommends that organizations with many concurrent users avoid the use of the Any search type. Users can achieve the same search results while maximizing system performance through the use of targeted searches or Super Pills. |
|
Dates |
Searches for metadata types such as Date Created or Date Modified. In some cases the Dates category might be limited to a date value only, while in other cases you might be prompted to enter both date and time values. When selecting a search type that requires you to enter a date or a date range, the app displays a calendar that you can use to select your values. For more information, see Working with Date Fields. |

Markers and Segments (simple) |
Select this option to limit your search results to include only assets that match marker metadata (comments), Asset Management stratum, segment data created through the Log app, or segment data created through Transcribe. These types of attributes are also known as Time-Based metadata (TBMD). n If you add two or more Markers and Segments pills to the Search using the and (&) operator, each search term must appear in the same marker or segment. If the search terms appear in different markers or segments in the same asset, the asset is not returned in the search results. You can select the higher lever "Markers and Segments" option to search for all search types within this category, or you can specifically select one of the following secondary search types:
This search type might also return strata annotation associated MediaCentral | Analytics. This is an optional feature that provides a framework for automated content indexing, such as facial detection, scene recognition, and speech-to-text conversion, by using third-party capabilities. If your system is licensed for this feature, the Search Type menu might include a number of additional options. For more information on installing and configuring this feature, see the Avid MediaCentral | Analytics ReadMe on the Avid Knowledge Base. |
|
Markers and Segments (advanced) |
This menu item provides access to alternative versions of the Markers and Segments search types. For example if you select the Transcript option under the simple category, you are presented with a single-value field.
If you select the Transcript search type from the advanced section, you are presented with menu that allows you to enter one or more values to further narrow your search.
If you enter 2 or more values in an advanced pill, you are essentially creating a compound search. Values that are included in the pill must be found in the same marker, segment, or layer. For example consider a transcript that has two speakers and the phrase "Avid". If you search for Speaker 1 and Avid, the search would return a hit only if Speaker 1 says "Avid". It would not return a hit if Speaker 2 says "Avid". Unlike Markers and Segments (simple), you cannot select the higher lever "Markers and Segments" option to search for all search types within this category. n If you are integrated with MediaCentral Asset Management, the advanced category might include a much longer list of older strata types. |
|
Metadata |
This is the default selection for each new search term. Searches for text-based metadata - including both statically assigned values such as format and resolution, as well as user-defined values such as asset names. This search type does not return time-based metadata such as information included in marker data. |
|
Phonetic
Phonetic |
The Phonetic search type is available if your MediaCentral Cloud UX system is licensed for MediaCentral Phonetic Index. This metadata is created by phonetically analyzing assets that include one or more audio tracks. Phonetic-based searches are available in two varieties: fast or accurate. The fast version of the search might provide a larger number of phonetic hits, but with less accuracy. Inversely, the accurate search provides fewer results, but the hits have a much higher probability of matching your search criteria. For more information, see Using the Phonetic Search Type. |
|
Time |
Associated with secondary search types, the Time search type allows you to search for assets at a given time, without an associated date value. |
|
Super Pill |
Allows you to combine multiple search types into a single search pill. For more information, see Using Super Pills. |
Whenever you add two or more terms using the same search type, the search bar displays the same color for each pill. For example two metadata terms might both be colored blue, but a phonetic term would be displayed using a different color. This color-coding system can help you more easily identify multiple search terms of the same type.
To change the search type:
-
Click on the search type icon on the left side of any search term.
The Search Type menu appears below the term with possible options.
-
Select a new search type from the menu.
The term is updated to reflect the change, as indicated by the search type icon.
