when i use # in url, the params go before the hashtag

when i use # in url, the params go before the hashtag

i write this code in the snippet html 

<form action='/guillaumon/gestao-de-tarefas#Page:Kanban_Lead_4_1'
                      target='_self'>
                      <label for="Pesquisa">Pesquisa:</label>
                      <input type="text" id="pesquisa" name="pesquisa">
                      <input type="submit" value="Submit">
                      </form>

but every params i pass, they go to before the "#" and i cant get the results i want, how to solve this problem?

i have this

"/guillaumon/gestao-de-tarefas?pesquisa=teste#Page:Kanban_Lead_4_1"

and i need to make it look like

"/guillaumon/gestao-de-tarefas#Page:Kanban_Lead_4_1?pesquisa=teste"
