SAP user Master data query

Hi,
In User master data I use "Search term 1" to input data. I'm building a query in SQVI and linked tables USR02 + USR21+ADR6+ ADRC to retrieve the necessary data for my query. However, although search term is populated in user master data I'm not getting any results from this field when i execute the query.
Can someone confirm if ADRC is the adequate table for search tearm in User masterdata?

Thank you
