php - Elasticsearch和Symfony搜索单词的一部分

Question

我是Elastic Search的新手，也许您可​​以为我提供帮助:

因此，我有symfony和Elasticsearch(FOSElasticaBundle)。

如果我正在搜索标题中的完整单词-一切正常(例如，如果键入“hello”，则将在“hello”世界所在的位置获得结果)。

But problem is, that, I want to be able to search for a part of word too, for example if I type "hel" I want to get result where "hel" is part of a word.

我的config.yml

fos_elastica:
    clients:
        default: { host: localhost, port: 9200 }
    indexes:
        app:
            client: default
            settings:
                index:
                    analysis:
                        analyzer:
                            custom_search_analyzer:
                                type: custom
                                tokenizer: standard
                                filter   : [standard, lowercase, asciifolding]
                            custom_index_analyzer:
                                type: custom
                                tokenizer: standard
                                filter   : [standard, lowercase, asciifolding, custom_filter]
                        filter:
                            custom_filter:
                                type: edgeNGram
                                side: front
                                min_gram: 1
                                max_gram: 20
            types:
                book:
                    mappings:
                        Author:
                        isbn:
                        title: { analyzer: custom_search_analyzer, analyzer: custom_index_analyzer, filter: custom_filter, type: string }
                    persistence:
                        driver: orm
                        model: VienasVienas\Bundle\BooksBundle\Entity\Book
                        provider:
                        listener:
                        finder:

我的PHP函数

public function indexAction(Request $request)
{
    $finder = $this->get('fos_elastica.finder.app.book');
    $searchTerm = $request->query->get('q');

    $searchQuery = new \Elastica\Query\QueryString();
    $searchQuery->setParam('query', $searchTerm);
    $searchQuery->setDefaultOperator('AND');

    $books = $finder->find($searchQuery);
    return array(
        'entities' => $books
    );
}

有人可以帮忙吗？

所以我只是忘记为字段添加setParam ...

    $searchQuery->setParam('fields', array(
        'Author',
        'title',
        'isbn',
    ));

现在一切正常!
