Create an Oracle Database 12c query that will be called from a Java web service

I have a web service in Java that performs searches on an Oracle 12c Database. The problem is I have a CONTAINS() search:
String query = "select * from user.my_table WHERE CONTAINS(my_clob_field, '" + searchString + "', 1) > 0";
but I also want to get the index(es) of the search word or phrase within each result.
Your task is to come up with a query, that can be called from a Java web service, that will do what the above query does, but will also return the indexes of the search word or phrase.
Background:
Currently what I've tried is to take each of the returned search results and go through them performing a REGEX search in Java to find the start and stop indexes needed to highlight the search result on the front end.
This works fine for regular text but if the requirement is that the user can search for any random arrangement of any characters (i.e. #<(F#><$*>/\./#&!)#}{}][s fdf) the Java search needs to also find that exact string and return the start and stop index.
I escape out any special characters for the Oracle search, but an entirely different set of rules is needed for the Java search to find the index. Trying to get them to match up has turned out to be a nightmare and typically the Java REGEX search doesn't find the same occurrences that the Oracle Database CONTAINS() search finds. I believe there should be some simple way to also get the indexes of the occurrences of the search word (or phrase).
Your task is to come up with a query, that can be called from a Java web service, that will do what the above query does, but most importantly, will also return the indexes of the search word or phrase.
For example, say one of the records from a CONTAINS() query has 3 occurrences of the search word in it. Your query would also return the start and stop indexes of each of the three occurrences within the CLOB field.
