Hi Kris,
there are features like http://scn.sap.com/community/abap/hana/blog/2015/03/10/spotlight-on-the-enhanced-search-f4-help or the ALV with IDA (see the details about fault-tolerant text search features in Data Retrieval - SAP GUI - SAP Library), but apart from that you're right.
As Open SQL is open to all SAP supported DBs and apart from one exception (views with parameters) the CDS views as well, the usage of Fuzzy Search is limited to native SQL in ABAP.
Cheers,
Jasmin
