[GENERAL] Special index for "like"-based query - Mailing list pgsql-general

Hello,

in Postgresql 9.6 we have a query running on a very large table based, in some cases, on a like statement:

... WHERE FIELD='CODE' OR FIELD LIKE 'CODE_%'

Which type of index can i create to speed to the search when the "like" case happens?

Thank you!
