Use PHP and Xunsearch to realize the automatic completion function of search keywords

The automatic completion function is when the user enters the search keyword, prompts and supplements based on the existing data to improve the accuracy of the search sex and user experience. In PHP development, this function can be achieved with the help of Xunsearch search engine library. This article will introduce how to use PHP and Xunsearch to implement the automatic completion function of search keywords.

First, we need to build a Xunsearch search engine service. You can use the installation package and tutorial provided by Xunsearch's official documentation to complete the setup. After the construction is completed, you need to use the SDK provided by Xunsearch to connect to the search engine service.

In PHP, you can use the classes provided by Xunsearch to perform search operations. The following is a simple sample code:

search; // 获取搜索对象 $word = $_GET['keyword']; // 获取用户输入的关键词 $search->setLimit(10); // 设置需要返回的搜索结果数量 $query = new XSTokenizerScws($word); // 创建一个分词器 $search->setQuery($query); // 设置搜索关键词 $search->setFuzzy(true); // 设置模糊搜索 $docs = $search->search(); // 执行搜索操作 $result = array(); foreach ($docs as $doc) { $result[] = $doc->title; //将搜索结果的标题添加到结果数组中 } echo json_encode($result); // 将结果数组转换为JSON格式并返回给前端

The above code implements fuzzy search based on the keywords entered by the user and returns the title of the search results. Among them,$xs->searchobtains a search object,$search->setQuery($query)sets the search keyword,$search-> setFuzzy(true)enables fuzzy search,$search->search()performs the search operation.

In order for the auto-complete function to take effect, we need to conduct real-time searches and prompts when the user enters the input box. This can be achieved using AJAX technology. The following is a simple front-end code example:

The above front-end code implements real-time search and prompts by listening to theinputevent of the input box. Whenever the user input changes, a GET request will be sent tosearch.phpon the backend, and the keywords entered by the user will be passed as parameters. The results returned by the backend are displayed on the page by dynamically generating
