I tried to review and my research gave the following results:
There are 4 types of changes in the files:

1. "as" versus "AS" are the non-functional cypher query style issues.
   • the following file needs to be edited, too, imo: fetch_full_text_search_index.cql (line 10) ❕️
2. "OPTIONAL CALL" are the changes to not raise server error when search query is not found
   • looks good. I couldn't find further instances with if-clauses before a Call, or further test instances where it could be missing ✅️
3. ":stableTargetId" can be used like this if the relationship doesn't need to be named for further usage in the query.
   • I guess it looks like this is the case ✅️
4. expand the tests for unfound queries:
   • looks good, too. ✅️

yep, this is just to distiguish between cypher keywords and made-up variable names, etc.

   * the following file needs to be edited, too, imo: fetch_full_text_search_index.cql (line 10) ❕️

good catch, thank you! fixed in a171b60

2. "OPTIONAL CALL" are the changes to not raise server error when search query is not found

exactly.

3. ":stableTargetId" can be used like this if the relationship doesn't need to be named for further usage in the query.

also exactly right.

4. expand the tests for unfound queries:
