Answer 1

1-using the manual form
just put request.GET.search in the value, nothing to change in your views
template
<form method="GET">
Search: <input type="text" name="search"
value="{{ request.GET.search }}">
<input type="submit" value="Search">
</form>
2 - using forms
What about if you use form? Well, we will use session variable here.
forms.py
from django import forms
class SearchForm (forms.Form) :
search = forms.CharField(max_length=100)
template
<form method="GET">
{{ form.as_p }}
<input type="submit" value="Search">
</form>
views.py
from django.shortcuts import render
from app_name.forms import SearchForm
def myview(request):
if request.GET.get('search'):
request.session['search'] = request.GET.get('search')
#do query searching here
form = SearchForm(initial={
'search': request.session.get('search')
})
return render(request, 'search_page.html', {
'form': form
})

Answer 2

If you are working with a form object, then in your view, you can do:
def myview(request):
if request.method=="GET":
form = SearchForm(request.GET)
return render(request, 'searchPage.html', {'form':form,})
