搜索包是一个提供轻量级搜索引擎的包。它基于 lucene 搜索库并包含 zend 组件。

安装

1. 在 AppKernel 中

    new Ivory\LuceneSearchBundle\IvoryLuceneSearchBundle(),
    new Lpi\Bundle\SearchBundle\LpiSearchBundle(),

配置

1. 在 app/config/config.yml 中

    ivory_lucene_search:

        # Index identifier
        search_index:
            # Path to store the index (Required)
            path: %kernel.cache_dir%/search_index

            # Index analyser (Optional)
            # See http://framework.zend.com/manual/en/zend.search.lucene.charset.html
            analyzer: ZendSearch\Lucene\Analysis\Analyzer\Common\Text\CaseInsensitive

            # Max Buffered documents (Optional)
            # See http://framework.zend.com/manual/en/zend.search.lucene.index-creation.html#zend.search.lucene.index-creation.optimization.maxbuffereddocs
            max_buffered_docs: 10

            # Max merge documents (Optional)
            # See http://framework.zend.com/manual/en/zend.search.lucene.index-creation.html#zend.search.lucene.index-creation.optimization.maxmergedocs
            max_merge_docs: 10000 # (default: PHP_INT_MAX)

            # Merge factor (Optional)
            # See http://framework.zend.com/manual/en/zend.search.lucene.index-creation.html#zend.search.lucene.index-creation.optimization.mergefactor
            merge_factor: 10

            # Index directory permission (Optional)
            # See http://framework.zend.com/manual/en/zend.search.lucene.index-creation.html#zend.search.lucene.index-creation.permissions
            permissions: 0777

            # Auto optmized flag (Optional)
            # If this flag is true, each time you request an index, it will be optmized
            # See http://framework.zend.com/manual/en/zend.search.lucene.index-creation.html#zend.search.lucene.index-creation.optimization
            auto_optimized: false

            # Query parser encoding (Optional)
            # See http://framework.zend.com/manual/en/zend.search.lucene.searching.html#zend.search.lucene.searching.query_building.parsing
            query_parser_encoding: "UTF-8" # (default: "")

1. 对于您想要索引的每个实体，您需要添加 "Lpi\Bundle\SearchBundle\Model\IndexableInterface"，一个实体需要具有以下 4 个方法：
   • getId()
   • getTitle()
   • getSlug()
   • getDescription()
2. 在 app/config/config.yml 中

    lpi_search:
        mappings: 
            - { value: ApplicationLpiEventBundle:Event , path: programmation_detail} #name of the entity you want to be indexed

使用

现在您已经注册了所有索引，并且想要使用它们，非常简单！

例如，在控制器中

/**
 * @param Request $request
 * @return array
 * @Route("/search", name="path_search")
 * @Template()
 * @Method({"GET", "POST"})
 */
public function searchAction(Request $request) {
    $results = null;
    if ($request->request->has('term') and '' !== $request->request->get('term')) {
        $results = $this->get('lpi_lucene.search')->search($request->request->get('term'));
    }

    return array(
        'results' => $results
    );
}

并在您的视图中渲染，例如

{% if results is defined and results|length > 0 %}
    {% for result in results %}
        <div class="col-xs-12">
            <a href="{{ result.url }}" title="{{ result.title }}">
                {{ result.title }}
            </a>
        </div>
    {% endfor %}
{% else %}
    <div class="alert alert-warning">{{ 'search.result.nothing'|trans({}, 'messages') }}</div>
{% endif %}
