Regex to match word in the middle

Question

My current regex

^Service\.LT\.fix\.log$

matches the below string

Service.LT.fix.log

How would I change regex so any word before and after LT should pass.

The regex should pass all the below cases:

Service.LT.fix.log
Service.BeforeLT.fix.log
Service.LTAfter.fix.log

I tried

^Service\..+?LT.+?\.fix\.log$

but that did not work.

Use `.*?` instead of `.+?`, that will allow the matching of *nothing* — Jerry, Jan 16 '19 at 12:54
The `+` quantifier means 1 or more, whereas `*` means 0 or more. Using `.+?` in your regex is like saying there must be at least *something* before `LT`, but this *something* cannot be *nothing*, it needs to be at least of length 1. — Jerry, Jan 16 '19 at 13:00
