I saw this exact same problem posted by someone else, but the issue was archived without a resolution. (Searching is not working on code editor, and Data Dictionary/PLSQL/Search Source Code/Text Search -19.1 SQL Developer )
Re-raising the issue because it hasn't gone away, and I still don't see an answer.
I'm using the "Search Source Code" option under All Reports / Data Dictionary Reports / PLSQL
This no longer finds any rows. I still have a 17.4 install on my machine, and the same search yields the results I am looking for. The author of the archived post had similar problems. They were using 18.3 and working fine. Then, no results in 19.2
NOTE: this was using the "Text Search" option (NOT the "PL/SQL Object Name" )
