• CDEs follow the ISO/IEC 11179 standard, so you can search for data elements using ISO/IEC 11179-based attributes.
• 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. 
• For some fields, you can adjust the search scope (with options such as IS NULL, IS NOT NULL, NOT LIKE, Exact Phrase Match, 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 only CDEs that fulfill all the criteria are returned.
• To reset a list of values, click the Clear Values icon next to that list. 
• When you remove or change search criteria, the system does not update search results until you click Apply Filter again.
• (TBD: Are some fields case-sensitive and others case-insensitive? If so, which ones are which?)

To perform a data element search:

1. Open a supported browser:
   • TBD
   • TBD

2. Navigate to the following portal:

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

   The home page appears. 

3. 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. 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.

4. 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.

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

   Field	Instructions
   Enter Search String	Enter a search string, complete or partial. The search is not case-sensitive. This field searches 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 public ID. You cannot use wildcards in this field.
   CDE Long Name	Enter a CDE long name, complete or partial. The search is not case-sensitive. (To adjust search scope, click the Advanced Filter icon.)
   Multiple Public ID Search	Enter a public ID, complete or partial. To specify multiple public IDs, click the Advanced Filter icon. In the adjacent field, select One of the Words. Enclose each ID in periods and separate each value with a space (for example: .5. .6. .10.). (TBD: Considering the word "Multiple" in the field label, I'm surprised users have to take these extra steps.)
   CDE Short Name	Enter a CDE short name, complete or partial. (To adjust search scope, click the Advanced Filter icon.)
   Latest Version	Data elements are assigned version numbers by the context administrator. Select one of the following options: To search for the latest version of the CDE, select Yes. To search for all versions except the latest version, select No. To search for all versions, clear this field. (That is, set it to Select Value.)
   Owned By	Specify the context that has administrative authority to edit and update the CDE.
   Registration Status	Registration status filters your results based on the data element registration status. For details, refer to Registration Status. (link TBD).TBD: I intend to move this page at the time of release.)
   Workflow Status	Workflow status filters your results based on the administrative workflow status of the data element. In most cases, you will want to search for released data elements, but any status is available.  For For details, refer to Workflow Status. (link TBD).TBD: I intend to move this page at the time of release.)
   Origin	Specify the source of the administered item.
   Origin Description	Specify a search string for the origin description.
   Program Area	Select a program area.
   Created By	Specify the name of the person who created the item.
   Last Modified By	Specify the name of the person who last modified the item. (To adjust search scope, click the Advanced Filter icon.)

6. In the fields that have a Select a Value icon, you can select one or more values. Click the Select a Value icon next to the field. A Reference Data Panel appears. 

   • To select one value: Click the value name. The value name appears in the field. 
   • To select one or more values: Click the checkbox for each row you want to include. Click Set Values. The field indicates how many values you have set. 

7. For date criteria, click the Audit Columns icon and specify dates as described in the following table: 

   Field	Instructions
   Date Created	Click the calendar icon and select the date on which the item was created.
   Date Last Modified	Click the calendar icon and select the date on which the item was last modified.

   To adjust search scope, click the Advanced Filter icon and consider the following options:

   • The list to the left of each date field allows you to search for items greater than, less than, and/or equal to the date you specify. (TBD: Does ">" mean dates later than the specified date?)

   • The list to the right of each date field allows you to specify whether the date field is NULL or NOT NULL.
   • The check box below each date field allows you to specify a date range. 
8. You can also specify an explicit "where" clause. Click the Advanced Filter icon. Under Filter Options, select a column and then click >>. (TBD: What would the user do next?)
