How to setup live search in custom OcStore theme?

Question

opencart

Good afternoon.
There is a site on the OcSore 2.3.0.2.1 engine and the "Porto" theme is installed on it + the Simple 4.9.4 module is installed
When you try to install on the "live search" modules, the search string does not react to entering values.
If you switch the store to the default theme, then the "live search" works.
Tell me where to dig and where you can correct?
