The search interface was rebuild and offers several options.

• +namespace:'study-name' reduces the search to elements in one study.
• +variable:xyz and +dataset:xyz can be used to look for specific variable names or variables from one specific dataset.
• Wildcards (*) can be used both on generic search terms (e.g., politic* matches both "politic" and "political") and within fields (e.g., variable:ap01* matches "ap0101" or "ap0102")

Example: Search for keywords starting with "politic" in the SOEP-Core dataset "ap":

+namespace:'soep-core' +dataset:ap politic*
