• 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 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 (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. 
• The system processes search criteria as AND statements, so the results include only items that fulfill all the criteria.
• To reset a list of values, click the Clear Values icon next to that list. 
• If you clear a field, or if you leave a field at its default setting, the system does not limit the search by that criterion.
• You can specify the number of results returned: Type a number in the Number of Rows field and press <Enter>. (TBD: In legacy caDSR user documentation, the 2 - Searching for Administered Items page says, "During searches of the NCI Enterprise Vocabulary System, the maximum number of search results returned from the Metathesaurus is 750." Is this statement true & relevant when searching for CDEs, forms, & other administered items in OneData?) 
• When you remove or change search criteria, the system does not update search results until you click Apply Filter again.
