If search results of two consecutive searches in "Find & replace" are equal, the second search result is not identifiable.

Steps to reproduce:

1. Enter search string (with at least one occurence in code) in "Text to find"
2. Hit "Search All"
=> Result "n item(s) found"
3. Enter another search string (with the same amount of occurence in code) in "Text to find"
4. Hit "Search All"

Observed behavior:
Result doesn't change. It is unpredictable, whether search was successful or somehow stuck.

Expected behaviour:
Result should be immediately reset when "Text to find" is changed. This way the user is able to distinguish equal search results from each other.

I cannot immediately reproduce this. The search hits from the 1st search are replaced by the search hits the 2nd search.

Can you let me know your exact PL/SQL Developer version from the Help > About screen?

My version is 15.0.2.2054 (64 bit).

And yes, in case there are findings in the displayed part of the code, you'll see the change of findings corresponding to the search string. But there is a good chance that you don't have any match in display. So it still would be an improvement to indicate a new search by resetting the search result in "Find & replace", when entering a new search string.
