This issue is resolved in the following releases:

Enterprise Vault 10.0.1
http://www.symantec.com/docs/TECH147787

Enterprise Vault 9.0.4
http://www.symantec.com/docs/TECH147785

Two possible workarounds exist to obtain the search criteria for DA 9.0 through 9.0 SP3.

Workaround 1:

1) Access the Reports tab in the DA Client.

2) Click 'New' to begin creating a new report.

3) Select the Searches option in the Type field's drop down selection.

4) Enter a name for the report in the Name field.

5) Enter a description of the report, if desired, in the Description field.

6) Click the Add option under the Report Parameters section.

7) Select the Case under which the search was run and click the OK button.

8) Click the Apply button to begin the report generation.

9) When the report status shows as Ready, click the Preview tab to view the report.

10) Scroll through the list of searches to find the search in question.  Note that moving through the pages may be necessary to locate the exact search desired.

11) Click on the search name to drill down to the search criteria.

12) Note the search criteria as needed by expanding each of the following sections as needed:

- Search Details -- provides the search type (scheduled or immediate), if the options 'Automatically accept search results' and 'Include items already in review'

     have been selected, and the schedule name if the search is a scheduled search.

- Date Range - provides the date range for the search.

- Search Terms - provides the contents of the 'To', 'From', 'To or From' fields and the 'Subject', 'Content' or 'Subject or Content' fields.

- Attachments - provides information on any specifications for attachments (i.e., number of attachments, type of attachments).

- Miscellaneous - provides information in the Miscellaneous section of the search, such as the 'Include only non-indexed items' option.

- Policies - provides information on any policy selections.

- Custom Attributes - provides information on any custom search attributes created for the search or application.

Workaround 2:

1) Hover the mouse over the name of the search.

2) Wait until the pop-up appears with the SearchID and CaseID.

3) Note the SearchID.

4) Access the DA Customer database through the SQL Server Management Studio

5) Run the following SQL query against the DA Customer database

SELECT XMLText FROM tblIntSearches WHERE SearchID = ## -- replacing ## with the SearchID noted in Step 3.

6) Right click on the XMLText output from the query and select the Copy option.

7) Open an empty NotePad document.

8) Paste the copied text into the document.

9) Reformat the text so that it is more easily read.   For example:

<SearchCriteriaDS xmlns="http://www.tempuri.org/SearchCriteriaDS.xsd">
     <SearchCriterias d2p1:Name="juser1"                      <-- UserID in Active Directory

                      d2p1:MinimumNumberRecipient="0"
                      d2p1:AutoAccept="false"                 <-- Automatically accept search results if "true" 
                      d2p1:SampleCap="-1"
                      d2p1:FreeformTargetsOnly="false"
                      d2p1:CustodianAddressOption="1"
                      d2p1:CustodianGroupDistributionListOption="1"
                      d2p1:IncludeDistributionListMembers="false" 
                      xmlns: d2p1="http://www.tempuri.org/SearchCriteriaDS.xsd">

                           d2p1:ID="15" />                    <-- AddressOwnerID in Custodian Manager database
          </SearchRecipients>
     <SearchDates d2p1:Operant="1">
          <SearchDate d2p1:From="0001-01-01T00:00:00Z"

                      d2p1:Operant="1"
                      d2p1:Type="1"
                      d2p1:RelativeDisplay="6"
                      d2p1:RelativeValue="0"
                      d2p1:DateIndexAttribute="0"
                      d2p1:UseHistoricalDatesForCM="false" />          <-- Will use historic data for Custodians and Custodian Groups if "true"
          </SearchDates>
     <RetentionCategories d2p1:Operant="0" />
     <Policies d2p1:Operant="0" />
     </SearchCriterias>
 </SearchCriteriaDS>

10) Save the NotePad document.

11) Review the document contents for the search criteria used. 

Note that the actual SMTP  Address(es) for the Custodian is not present in the XML Text field, nor is it present in any other field associated with the search in the tblIntSearches table.  This is due to the expectation that the Custodian's SMTP Address(es) and SMTP  Display Name(s) will be present in the Custodian Manager database tables.
