Dear Customer,
The error:
java.sql.SQLException: Failed SQL: /* ~~QC */ { sql..syntax}
[Mercury][SQLServer JDBC Driver][SQLServer]The execution of a full-text query failed. "The form specified for the subject is not one supported or known by the specified trust provider."
It is caused because the indexing engine was set up to run as an network admin user, which caused difficulties.
To fix please follow next steps
1. This error switch the indexing engine to run as local user account. (SQL server instance> SQL Server configuration manager>SQL server fulltext search ).
2. For SQL Server only (must be done by DBA):
A. In the Microsoft SQL Server Management Studio, right-click on the Project database.
B. Open a new Query Window.
C. Paste the following SQL statement into the query window, and click the Execute Button.
sp_fulltext_database disable.
D. Ask your DBA to delete the "QCFTCAT" item.
3. Rebuild the text search in Site Administration>Expand Domain> Select project details > Click Enable/Rebuild Text search button.
Cordially
