Suggestion and spell checker

Subscribing

You could add suggestions to apache solr this way
In apache_solr_views_query.inc in the execute function above the $response = $this->_solr_service ...

      //add spellchecking on a field
      if (variable_get('apachesolr_search_spellcheck', TRUE)) {
      	$this->_params['spellcheck.q'] = $view->exposed_input['text'];
      	$this->_params['spellcheck'] = 'true';
      }
      
      $response = $this->_solr_service->search($this->_query, $offset, $view->pager['items_per_page'], $this->_params);

Then in a custom module you could get the suggestions like this and call them from a block or something. (the apache solr views module stores the result so we can get it)

function get_suggestions() {
  $apachesolr_has_searched = apachesolr_has_searched();
  $response = apachesolr_static_response_cache();
  
  if ($apachesolr_has_searched && $response && variable_get('apachesolr_search_spellcheck', TRUE)) {
    $suggestions = get_object_vars($response->spellcheck->suggestions);
    if ($suggestions) {
      foreach ($suggestions as $suggestion) {
        foreach ($suggestion->suggestion as $part) {
          $options['query']['text'] = $part;
          $list[] = l($part, 'solr', $options);
        }
      }
    }
  }
  return theme('item_list', $list);
}

Perhaps this could be included in the module?

I think the right approach would be to attach the spellchecker suggestions to the exposed filter form. So in that form you would do something like

$form['suggestions'] = array(
'#type' => 'markup',
'#value' => theme('solr_views_suggestions', $response)

Then the default theme implementation for the suggestions could be an item list. And doing this allows some module to do a form_alter on the form and put '#access' => FALSE if they don't want suggestions.

Thats the approach I like.

Edit!

By exposed filter form, you're referring to the views-exposed-form.tpl.php, right?

Can anyone help explain this in more simple steps please?

Would love to see this functionality, right now the search field is a bit crippled on our site because of this....

I'm also anxiously waiting for this feature. Scott's approach seems fine.

We also need this feature on our site... subscribing.....

the path did not work for me, im also using exposed form to show the apache solr result and perform the search and i cant see the spellcheck and i really need it
