# 在 Halo 中实践全文搜索 主题端需全文搜索接口用于模糊搜索文章，且对效率要求极高。已经有对应的 Issue 提出，可参考：<https://github.com/halo-dev/halo/issues/2637>。 实现全文搜索的本地方案最好的就是 Apache 旗下开源的 [Lucene](https://lucene.apache.org/) ，不过 [Hibernate Search](https://hibernate.org/search/) 也基于 Lucene 实现了全文搜索。Halo 2.0 的自定义模型并不是直接在 Hibernate 上构建的，也就是说 Hibernate 在 Halo 2.0 只是一个可选项，故我们最终可能并不会采用 Hibernate Search，即使它有很多优势。 Halo 也可以学习 Hibernate 适配多种搜索引擎，如 Lucene、ElasticSearch、MeiliSearch 等。默认实现为 Lucene，对于用户来说，这种实现方式部署成本最低。 ## 搜索接口设计 ### 搜索参数 字段如下所示： - keyword: string. 关键字 - sort: string[]. 搜索字段和排序方式 - offset: number. 本次查询结果偏移数 - limit: number. 本次查询的结果最大条数 例如： ```bash http://localhost:8090/apis/api.halo.run/v1alpha1/posts?keyword=halo&sort=title.asc&sort=publishTimestamp,desc&offset=20&limit=10 ``` ### 搜索结果 ```yaml hits: - name: halo01 title: Halo 01 permalink: /posts/halo01 categories: - a - b tags: - c - d - name: halo02 title: Halo 02 permalink: /posts/halo02 categories: - a - b tags: - c - d query: "halo" total: 100 limit: 20 offset: 10 processingTimeMills: 2 ``` #### 搜索结果分页问题 目前，大多数搜索引擎为了性能问题，并没有直接提供分页功能，或者不推荐分页。 请参考： - <https://solr.apache.org/guide/solr/latest/query-guide/pagination-of-results.html> - <https://docs.meilisearch.com/learn/advanced/pagination.html> - <https://www.elastic.co/guide/en/elasticsearch/reference/current/paginate-search-results.html> - <https://discourse.algolia.com/t/pagination-limit/10585> 综合以上讨论，我们暂定不支持分页。不过允许设置单次查询的记录数（limit <= max_limit）。 #### 中文搜索优化 Lucene 默认的分析器，对中文的分词不够友好，我们需要借助外部依赖或者外部整理好的词库帮助我们更好的对中文句子分词，以便优化中文搜索结果。 以下是关于中文分析器的 Java 库： - <https://gitee.com/lionsoul/jcseg> - <https://code.google.com/archive/p/ik-analyzer> - <https://github.com/huaban/jieba-analysis> - <https://github.com/medcl/elasticsearch-analysis-ik> - <https://github.com/blueshen/ik-analyzer> ### 搜索引擎样例 #### MeiliSearch ```bash curl 'http://localhost:7700/indexes/movies/search' \ -H 'Accept: */*' \ -H 'Accept-Language: zh-CN,zh;q=0.9,en;q=0.8,en-GB;q=0.7,en-US;q=0.6,zh-TW;q=0.5' \ -H 'Authorization: Bearer MASTER_KEY' \ -H 'Connection: keep-alive' \ -H 'Content-Type: application/json' \ -H 'Cookie: logged_in=yes; adminer_permanent=; XSRF-TOKEN=75995791-980a-4f3e-81fb-2e199d8f3934' \ -H 'Origin: http://localhost:7700' \ -H 'Referer: http://localhost:7700/' \ -H 'Sec-Fetch-Dest: empty' \ -H 'Sec-Fetch-Mode: cors' \ -H 'Sec-Fetch-Site: same-origin' \ -H 'User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/107.0.0.0 Safari/537.36 Edg/107.0.1418.26' \ -H 'X-Meilisearch-Client: Meilisearch mini-dashboard (v0.2.2) ; Meilisearch instant-meilisearch (v0.8.2) ; Meilisearch JavaScript (v0.27.0)' \ -H 'sec-ch-ua: "Microsoft Edge";v="107", "Chromium";v="107", "Not=A?Brand";v="24"' \ -H 'sec-ch-ua-mobile: ?0' \ -H 'sec-ch-ua-platform: "Windows"' \ --data-raw '{"q":"halo","attributesToHighlight":["*"],"highlightPreTag":"<ais-highlight-0000000000>","highlightPostTag":"</ais-highlight-0000000000>","limit":21}' \ --compressed ``` ```json { "hits": [ { "id": 108761, "title": "I Am...
