Optimize query on table with 10 million transactions

Question

Is there a better way than showed below to retrieve the transactions from a table that contains more than 9 million transactions.
SELECT FROM TAB_COMM WHERE CARR_CD='ABC' AND POL_NUM LIKE 'HPA%';How to optimize this query to show results for policy starting with HPA? This query returns more than 1 million transactions. There are already many indexes on this table and not sure if adding index will work on LIKE operator?

Answer 1

Thanks for all the responses. So much to learn from you all!
I could understand that we may need to add another index to this table. Before adding one, please look into the existing ones:

Please advice.
