You can't have the same name twice. You need to change the name for one of
the followings:
path('customsearch/', views.search, name='search'),
path('customsearch/<str:params>/', views.search, name='search_xxx')
Reverse method requires a url identified by name parameter which must be
unique. Its looking for search and it find it on two places so you are
getting this error.
