Page History

When you search for Common for Common Data Elements (CDEs) in OneData, keep in mind the following points:

• CDEs follow the ISO/IEC 11179 standard, so you can search for data elements using ISO/IEC 11179-based attributes.
• For each field, the default is all values. For example, in the Latest Version field, the default behavior returns all versions.
• Searches are not case sensitive. Searches for Gene and gene return the same results.
• In any editable text field, enter a search string, complete or partial. This does not apply to numeric fields such as CDE Public ID. 
• In any editable text field, you can use a percent sign (%) as a wildcard. For examples, refer to Using Wildcards.  
• For some fields, you can adjust the search scope (you can specify with options such as IS NULL, IS NOT NULL, NOT LIKE, Exact Phrase Match,  All All Of The Words, or One Of The Words) by clicking the Advanced Filter icon. 
• In any editable text fields, you can use a percent sign (%) as a wildcard. For examples, refer to Using Wildcards - 2021-06-09. 
• The system processes search criteria as AND statements, so the results include only CDEs that fulfill all the criteria are returned.
• To reset a list of values, click the Clear Values icon next to that list. 
• You can specify the number of results returned: Type a number in the Number of Rows field and press <Enter>.
• When you remove or change search criteria, the system does not update search results until you click Apply Filter again.

3. Navigate to the following portal:

   https://wmonedata.nci.nih.gov/

   The home page appears. 

4. From the View menu, select Browse and then select one of the following options:

   • Data Elements - View/Browse: Search for data elements used by or owned by any context. 
   • NCI Standard Data Elements: Search within released data elements that are either owned by or used by the NCI Standards Context. This menu option is a shortcut to find all the data elements that NCI has deemed to be a NCI considers these data elements to be standard for the NCI. These elements are a subset of the data elements available in Data Elements- View/Browse.

   The corresponding page appears. (Logged in users can add pages like this to their favorites. For instructions, refer to Managing Your Favorites.)

5. If necessary, you can clear the saved filter from the upper right corner of the search criteria panel, or select a different one:

   • The default saved filter excludes retired (from Workflow Status), excludes test and training (from Owned By), and includes the latest version. 
   • Another saved filter excludes only test and training (from Owned By).
   • Another saved filter includes only test and training (from Owned By).
   • To clear the saved filter, set this field to Select a Filter.

6. Specify one or more search criteria, as described in the following table: 

   DateTBD

   Field	Instructions
   Enter Search String	Enter Type all or part of a search string, complete or partial. The search is not case-sensitive. (TBD: If possible, I'd like to include here a list or description of the fields in which the system searches when the user specifies a search term here.) . This field searches the concatenation of CDE Short Name, CDE Long Name, and any type of Question text. (To adjust search scope, click the Advanced Filter icon.)
   CDE Public ID	Enter a Specify the full numeric value for a single CDE public ID. (You cannot use wildcards in this fieldnumeric fields. )

(TBD: Considering the word "Multiple" in the field label, I'm surprised users have to take these extra steps.). The periods ensure an exact match to the public ID. Otherwise, this search treats the IDs as text and returns any public ID containing the specified value. For example, "5" returns any public ID containing "5". Also, if you have a column of IDs in a spreadsheet, and each ID is enclosed in periods, you can copy that column into this field. Image Added
