Searching Pages
|
|
===============
|
|
|
|
Wagtail provides a ``search`` method on the QuerySet for all page models:
|
|
|
|
.. code-block:: python
|
|
|
|
# Search future EventPages
|
|
>>> from wagtail.wagtailcore.models import EventPage
|
|
>>> EventPage.objects.filter(date__gt=timezone.now()).search("Hello world!")
|
|
|
|
|
|
All methods of ``PageQuerySet`` are supported by ``wagtailsearch``:
|
|
|
|
.. code-block:: python
|
|
|
|
# Search all live EventPages that are under the events index
|
|
>>> EventPage.objects.live().descendant_of(events_index).search("Event")
|
|
[<EventPage: Event 1>, <EventPage: Event 2>]
|
|
|
|

An example page search view
|
|
===========================
|
|
|
|
Here's an example Django view that could be used to add a "search" page to your site:
|
|
|
|
.. code-block:: python
|
|
|
|
# views.py
|
|
|
|
from django.shortcuts import render
|
|
|
|
from wagtail.wagtailcore.models import Page
|
|
from wagtail.wagtailsearch.models import Query
|
|
|
|
|
|
def search(request):
|
|
# Search
|
|
search_query = request.GET.get('query', None)
|
|
if search_query:
|
|
search_results = Page.objects.live().search(search_query)
|
|
|
|
# Log the query so Wagtail can suggest promoted results
|
|
Query.get(search_query).add_hit()
|
|
else:
|
|
search_results = Page.objects.none()
|
|
|
|
# Render template
|
|
return render(request, 'search_results.html', {
|
|
'search_query': search_query,
|
|
'search_results': search_results,
|
|
})
|
|
|
|
|
|
And here's a template to go with it:
|
|
|
|
.. code-block:: html
|
|
|
|
{% extends "base.html" %}
|
|
{% load wagtailcore_tags %}
|
|
|
|
{% block title %}Search{% endblock %}
|
|
|
|
{% block content %}
|
|
<form action="{% url 'search' %}" method="get">
|
|
<input type="text" name="query" value="{{ search_query }}">
|
|
<input type="submit" value="Search">
|
|
</form>
|
|
|
|
{% if search_results %}
|
|
<ul>
|
|
{% for result in search_results %}
|
|
<li>
|
|
<h4><a href="{% pageurl result %}">{{ result }}</a></h4>
|
|
{% if result.search_description %}
|
|
{{ result.search_description|safe }}
|
|
{% endif %}
|
|
</li>
|
|
{% endfor %}
|
|
</ul>
|
|
{% elif search_query %}
|
|
No results found
|
|
{% else %}
|
|
Please type something into the search box
|
|
{% endif %}
|
|
{% endblock %}
|
|
|
|
|
|
Promoted search results
|
|
=======================
|
|
|
|
"Promoted search results" allow editors to explicitly link relevant content to search terms, so results pages can contain curated content in addition to results from the search engine.
|
|
|
|
This functionality is provided by the :mod:`~wagtail.contrib.wagtailsearchpromotions` contrib module.
|
|
|
|
|
|
Searching Images, Documents and custom models
|
|
=============================================
|
|
|
|
Wagtail's document and image models provide a ``search`` method on their QuerySets, just as pages do:
|
|
|
|
.. code-block:: python
|
|
|
|
>>> from wagtail.wagtailimages.models import Image
|
|
|
|
>>> Image.objects.filter(uploaded_by_user=user).search("Hello")
|
|
[<Image: Hello>, <Image: Hello world!>]
|
|
|
|
|
|
:ref:`Custom models <wagtailsearch_indexing_models>` can be searched by using the ``search`` method on the search backend directly:
|
|
|
|
.. code-block:: python
|
|
|
|
>>> from myapp.models import Book
|
|
>>> from wagtail.wagtailsearch.backends import get_search_backend
|
|
|
|
# Search books
|
|
>>> s = get_search_backend()
|
|
>>> s.search("Great", Book)
|
|
[<Book: Great Expectations>, <Book: The Great Gatsby>]
|
|
|
|
|
|
You can also pass a QuerySet into the ``search`` method which allows you to add filters to your search results:
|
|
|
|
.. code-block:: python
|
|
|
|
>>> from myapp.models import Book
|
|
>>> from wagtail.wagtailsearch.backends import get_search_backend
|
|
|
|
# Search books
|
|
>>> s = get_search_backend()
|
|
>>> s.search("Great", Book.objects.filter(published_date__year__lt=1900))
|
|
[<Book: Great Expectations>]
|
