php - 使用 Laravel Scout 时突出显示搜索结果

问题描述

在我的应用程序中，我使用Laravel Scout和TNTSearch 驱动程序在我的站点导航中创建一个搜索栏，该搜索栏连接到搜索方法。

search 方法搜索一堆不同的模型并将找到的内容返回给视图。

这是方法：

/**
 * Perform a search given what the user entered into the search box.
 * Uses Laravel Scout to do initial search but because the use of WHERE is limited,
 * we use a filter function instead, on each collection.
 *
 * @param Request $request
 * @return void
 */
public function search(Request $request)
{
    // The search string entered
    $search = $request->get('q');

    // Laravel Scout search() method
    $users = User::search($search)->get();
    $articles = Article::search($search)->get();
    $events = Event::search($search)->get();
    $files = FileMetaData::search($search)->get();

    // The date and time as of right now
    $today = Carbon::now();

    /**
     * Below are the filters in place for each model search
     * 1. News articles must be open
     * 2. \Events are split into open and closed
     */
    $articles = $articles->filter(function ($articles) {
        return $articles->published === 'published';
    });

    $upcomingEvents = $events->filter(function ($events) use ($today) {
        return $events->startDate->gt($today);
    });

    $pastEvents = $events->filter(function ($events) use ($today) {
        return $events->startDate->lt($today);
    });

    $userCount = count($users);
    $articleCount = count($articles);
    $eventCount = count($events);
    $upcomingEventCount = count($upcomingEvents);
    $pastEventCount = count($pastEvents);
    $fileCount = count($files);

    return view('pages.search.index', compact('search', 'users', 'articles', 'upcomingEvents', 'pastEvents', 'userCount', 'articleCount', 'upcomingEventCount', 'pastEventCount', 'files', 'fileCount'));
}

如您所见，我正在使用 Scout 的search()功能来搜索每个模型，然后对结果添加一些额外的约束，然后再将它们返回到我的视图中。

视图本身

在此处输入图像描述

我希望顶部突出显示的文本也可以在适当的位置突出显示搜索结果本身，但我似乎在文档中找不到任何关于将 TNT Highlighter 类与 Laravel 一起使用的内容。

通过 Laracasts 论坛拖网，我发现了这个：https ://laracasts.com/discuss/channels/laravel/algolia-highlighting-in-laravel-53?page=1

兴趣点

<?php

use TeamTNT\TNTSearch\TNTSearch;

$articles = Article::search($searchString)->get();
$tnt = new TNTSearch;

$articles = $articles->map(function($article) use ($searchString, $tnt) {
    $article->title = $tnt->highlight($title, $searchString, 'em'),
});

就我而言，每个结果集都需要这个片段吗？

更新：

$articles = Article::search($search)->get();

/**
     * Declaire where highlighting should occur for each collection
     */

    // Articles
    $articles = $articles->map(function($article) use ($search, $tnt){
        $article->title = $tnt->highlight($article->title, $search, b, [
            'simple' => false,
            'wholeWord' => false, 
            'tagOptions' => [
                'class' => 'search-term',
                'title' => 'test'
            ]
        ]);

        return $article;
    });

解决方案

我不熟悉 TNT 荧光笔，但如果你想尝试自己的方法，你可以使用这样的东西：

/**
* @$str = The string to highlight
* @$search_term = The term we are looking for in $str
**/
function highlightString($str, $search_term) {
    if (empty($search_term))
        return $str;

    $pos = strpos(strtolower($str), strtolower($search_term));

    if ($pos !== false) {
        $replaced = substr($str, 0, $pos);
        $replaced .= '<em>' . substr($str, $pos, strlen($search_term)) . '</em>';
        $replaced .= substr($str, $pos + strlen($search_term));
    } else {
        $replaced = $str;
    }

    return $replaced;
}

只是不要忘记设置<em>标签的样式
