Page History

...

1. Log in as described in Logging In via the GUI. The Dashboard appears.

2. Select a method:

   • If you want to perform a new search: In the left panel, click Search.
   • If you want to edit an existing saved search: In the Dashboard, locate the row for the saved search you want to edit. In that row, click Edit. 

   The Search page appears. 
   
   

3. Specify whether you want to search for a collection or a data object (also known as a data file). This selection clears any previous selections in other fields. 
4. Specify at least one metadata criterion:
   
   
   1. (Optional) Select the hierarchy level in which you want to search. The system updates the list of available attributes names. If you do not select a level, the system performs the search at all levels. This selection clears any previous selection in the Attribute Name field. 
   2. (Optional) Select an attribute name.

   3. Select an operator. The following table describes the available options:

      Advanced Tables - Table Plus
      sortColumn 1 columnTypes H
      # Operator Description Example 7 < Less than To find records with less than 10 as an attribute value, specify "10" with the < operator. 5 > Greater than To find records with greater than 10 as an attribute value, specify "10" with the > operator. 2 LIKE Contains To find records with "cell" or "multicellular" as an attribute value, specify "cell" with the LIKE operator. 1 = Equal to To find records with exactly 10 as an attribute value, specify "10" with the = operator. 3 != Not equal to To find records with anything other than 10 as an attribute value, specify "10" with the != operator. 6 <= Less than or equal to To find records with less than or equal to 10 as an attribute value, specify "10" with the <= operator. 4 >= Greater than or equal to To find records with greater than or equal to 10 as an attribute value, specify "10" with the >= operator. 8 Date greater than or equal to Date greater than or equal to To find records with a date later than or equal to December 31, 2018 as an attribute value, specify "12-31-2018" with the "Date greater than or equal to" operator. 9 Date less than or equal to Date less than or equal to To find records with a date earlier than or equal to December 31, 2018 as an attribute value, specify "12-31-2018" with the "Date less than or equal to" operator.

   4. For each non-date operator, specify a value. Keep in mind the following points:
      
      • The system ignores capitalization in this field. For example, "SMITH" and "smith" produce the same results.
      • The system recognizes an underscore character (_) as a wild card for any single character.
      • The system recognizes a percent character (%) as a wild card for any number of characters (zero, one, or more).
   5. For each date operator, specify a date. You can select a date from the calendar or type a value. The system assumes the date format in the records of interest is "MM-DD-YYYY HH24:MI:SS" (for example "03-29-2019 08:52:51").
5. (Optional) Click Add Criteria and repeat the previous step. The system assigns IDs to the metadata criteria (A1, A2, and so on).
6. (Optional) Click Advanced Search and specify a search query. Keep in mind the following points:
   • Specify the search IDs for the metadata criteria you have already specified. 
   • Use one or more logical operators (capitalized as AND, OR). 
   • Consider using parentheses. The system assesses the expressions within parentheses first. 
   • Consider the following example: (A1 OR A2) AND (A3 OR A4)
7. (Optional) Click Detailed results. The Path, Download, and Permission columns are always available in the search results for both collections and data files. If you proceed with the detailed results option, the results page will include the following additional columns: 
   • Columns for UUID, Registered by, Collection Type (for collections), Checksum (for data files), and Created On
   • Columns for self metadata and parent metadata
8. Click Search. The search results page appears. Keep in mind the following points:
   • If you have more than one metadata criterion and have not specified a search query, the system combines your criteria with AND, narrowing your search. 
   • For instructions on exporting, sorting, filtering, and navigating the search results page, refer to Using Search Results and Other Lists in the GUI - 20190920.
   • Consider saving your search, as described in Saving a Search via the GUI - 20190920. 

If you do not select a level, the system performs the search at all levels.
