Hi Steven,
By design, the enhanced search functionality limits searches to 60 characters. For data types that allow fewer than 60 characters, then enhanced search expands the field to allow for 60 characters.
Does that answer your question? In the end, are you able to select the right value from the drop-down list?
A field that accepts 110 characters sounds like a free text field that shouldn't really be searched on... Depending on your use case, perhaps you should disable enhanced search for this field. Alternatively, in the SAP client settings you can disable enhanced search, or set it to be only enabled with a key press.
As for the search results, these are what are returned by HANA. The search results are not configurable, or at least they weren't configurable when we implemented the feature. It was not possible for HANA to tell us what keywords matched for a row or why it returned a particular row. So as you have noticed, the keyword highlight in the drop-down rows is just a guess.
Using "fuzzy search" instructs HANA to also search for words similar to the search terms. For example, searching for "world" might return results with "word" or "worlds" in them. I would expect more search results to be returned when fuzzy search is enabled.
I hope that helps!
Best Regards,
