I tried with a GIST-like index and queries improves a lot, thank you!
 
Furthermore, this type of index is also suitable for a timestamp query, where we can mix date and time parameters?

Thank you again!

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?
