title: knp paginator bundle filtration settings
body: <p>I use this bundle in symfony 4, my filtering code looks like this </p>
  
  <pre><code>{{ knp_pagination_filter(paginator, {
                      't.code': 'Code'
                  }) }}
  </code></pre>
  
  <p>as well as my settings file in the 
  <strong><em>/conf/ directory</em></strong></p>
  
  <pre><code>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
  </code></pre>
  
  <p>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"</p>
  
  <p><strong><em>where I can set the filter type WHERE '%' + LOWER (param) + '%' LIKE LOWER (item.code)</em></strong></p>
