knp paginator bundle filtration settings

I use this bundle in symfony 4, my filtering code looks like this

{{ knp_pagination_filter(paginator, {
                    't.code': 'Code'
                }) }}

as well as my settings file in the /conf/ directory

knp_paginator:
    page_range:                 5          # default page range used in pagination control
    default_options:
        page_name:              page       # page query parameter name
        sort_field_name:        sort       # sort field query parameter name
        sort_direction_name:    direction  # sort direction query parameter name
        distinct:               true       # ensure distinct results, useful when ORM queries are using GROUP BY statements
        filter_field_name: filterField
        filter_value_name: filterValue
    template:
        pagination: '@KnpPaginator/Pagination/twitter_bootstrap_v4_pagination.html.twig'
        sortable: '@KnpPaginator/Pagination/sortable_link.html.twig' # sort link template
        filtration: '@KnpPaginator/Pagination/filtration.html.twig'  # filters template

No one faced with the fact that filtering is very rigidly tied to the value of the filter? for example: And the base has the values ​​"AppleJuice" and "Apple" when typing in the filter field "Apple", I do not see the value "AppleJuice", only "Apple"

where I can set the filter type WHERE '%' + LOWER (param) + '%' LIKE LOWER (item.code)

Exit, write your SQL query in your table service file
