What are your thought about this task? I mean that the search form and the 
search view are a subject 
of the final project's needs even if they could be as simple as issuing a 
search query and fill the 
results into the Django's list_detail.object_list generiv view.

Example:
{{{
from django.views.generic.list_detail import object_list
import xapian

class SearchForm(forms.Form):
    q = forms.CharField(max_length=200)

def search_view(request, queryset=EmptyQuerySet(), extra_context={}, **kwargs):
    if request.method == 'GET':
        form = SearchForm(data=request.GET.copy())
        if form.is_valid():
            q = form.cleaned_data['q'].strip()

            indexers = [Product.indexer, Client.indexer]
            indexer = CompositeIndexer(*indexers)

            # make a call for a possible spell correction of the search query by the full-text search 
system 
            results = indexer.search(q).spell_correction()
            corrected_query = results.get_corrected_query_string()
            queryset = results.prefetch()

            # prepare a list of normalized search terms to be used for highlighting
            results._query_parser.set_stemming_strategy(xapian.QueryParser.STEM_ALL)
            search_terms = list(results._query_parser.parse_query(results._query_str))

            extra_context.update({'corrected_query': corrected_query,
                                  'search_terms': search_terms,
                                  'q': q,
                                  })
    else:
        form = SearchForm()
    return object_list(request, queryset,
                       extra_context=extra_context,
                       page=request.GET.get('p', None),
                       **kwargs)
}}}

However, this stemmed search terms for highlighting the search results trick 
could be worth creating 
a special decoration over the django.views.generic.list_detail.object_list ...
