1. I use the xunsearch search function to build a document index for two tables, one is the article table and the other is the user table
2. My configuration file has two user.ini article.ini contents as follows

project.name = user
project.default_charset = utf-8
server.index = xxx:8383
server.search = xxx:8384

[id]
type = id

[nickname]
index = self
phrase = yes

[avatar]

[article_numbers]
type = numeric

[follow_numbers]
type = numeric

[fans_numbers]
type = numeric

[createtime]
type = numeric

project.name = article
project.default_charset = utf-8
server.index = xxx:8383
server.search = xxx:8384

[id]
type = id

[author]
type = string

[user_id]

[category_id]
index = self
tokenizer = full

[category]
type = both

[title]
type = title

[cover_url]
type = both

[content]
type = body

[reply_numbers]
type = numeric

[star_numbers]
type = numeric

[read_numbers]
type = numeric

[createtime]
type = numeric

3. Create an indexed document

    /**
     * 
     * @param $type string (update)(add)
     * @param $subject string (article)(user)
     * @return bool
     * @throws \XSException
     * @throws \think\exception\DbException
     */
    public function makedoc()
    {
        $request = Request::instance();
        $type = $request->param("type");
        $subject = $request->param("subject");
        switch ($subject){
            case "article":
                $map = [
                    "status" => ExtraConst::NORMAL
                ];
                $order = "collect_numbers desc,reply_numbers desc,star_numbers desc,read_numbers desc,id desc";
                $articles = Article::all(function ($query) use ($map, $order) {
                    $query->where($map)->order($order);
                });
                if (!$articles) {
                    return false;
                }
                $xs = new \XS(file_get_contents(ROOT_PATH . "docs" . DIRECTORY_SEPARATOR . "article.ini"));
                $doc = new \XSDocument();
                foreach ($articles as $article) {
                    $doc->setFields([
                        "id"            => $article->id,
                        "author"        => $article->author,
                        "user_id"       => $article->user_id,
                        "category_id"   => $article->category_id,
                        "category"      => $article->category,
                        "title"         => $article->title,
                        "content"       => $article->content,
                        "cover_url"     => $article->cover_url,
                        "reply_numbers" => $article->reply_numbers,
                        "star_numbers"  => $article->star_numbers,
                        "read_numbers"  => $article->read_numbers,
                        "createtime"    => $article->createtime,
                    ]);
                    if ($type === "add") {
                        $result = $xs->index->add($doc);
                    } elseif ($type === "update") {
                        $result = $xs->index->update($doc);
                    }
                }
                break;
            case "user":
                $map = [
                    "status" => "normal"
                ];
                $order = "id desc";
                $users = User::all(function ($query) use ($map, $order){
                    $query->where($map)->order($order);
                });
                if (!$users) {
                    return false;
                }
                $xs = new \XS(file_get_contents(ROOT_PATH . "docs" . DIRECTORY_SEPARATOR . "user.ini"));
                $doc = new \XSDocument();
                foreach ($users as $user){
                    $doc->setFields([
                        "id"                => $user->id,
                        "nickname"          => $user->nickname,
                        "avatar"            => $user->avatar,
                        "article_numbers"   => $user->article_numbers,
                        "follow_numbers"    => $user->follow_numbers,
                        "fans_numbers"      => $user->fans_numbers,
                        "createtime"        => $user->createtime,
                    ]);
                    if ($type === "add") {
                        $result = $xs->index->add($doc);
                    } elseif ($type === "update") {
                        $result = $xs->index->update($doc);
                    }
                }
                break;
        }

        if ($result) {
            echo "--------success  ----------";
        }
    }

4. Search for content based on keywords

    /**
     * 
     * @return array
     * @throws \XSException
     */
    public function search()
    {
        $request = Request::instance();
        $query = $request->post("key");
        $article_ini = file_get_contents(ROOT_PATH . "docs" . DIRECTORY_SEPARATOR . "article.ini");
        $user_ini = file_get_contents(ROOT_PATH . "docs" . DIRECTORY_SEPARATOR . "user.ini");
        //  
        $a_xs = new \XS($article_ini);
        $a_search = $a_xs->search;
        $a_search->setQuery($query)->setSort("createtime", true)->setLimit(20, 0);
        $a_docs = $a_search->search();
        $a_count = $a_search->count();
        //  
        $u_xs = new \XS($user_ini);
        $u_search = $u_xs->search;
        $u_search->setQuery($query)->setSort("createtime", true)->setLimit(20, 0);
        $u_docs = $u_search->search();
        $u_count = $u_search->count();
        dump($a_docs);
        dump($u_docs);die;
        // 

5. Use postman to test the interface

array(3) {
  ["code"] => int(1024)
  ["users"] => array(0) {
  }
  ["articles"] => array(4) {
    [1] => array(10) {
      ["id"] => string(10) "jo1gn7l9b8"
      ["title"] => string(36) ""
      ["author"] => string(22) "-"
      ["user_id"] => string(10) "xenp87gyvk"
      ["read_numbers"] => string(3) "123"
      ["reply_numbers"] => string(4) "3445"
      ["star_numbers"] => string(4) "1322"
      ["cover_url"] => string(41) "/uploads/cover/20180423/5add3c3664db9.jpg"
      ["content"] => string(57) ""
      ["createtime"] => string(11) "04-11 18:52"
    }
    [2] => array(10) {
      ["id"] => string(10) "jo1gn7l9b8"
      ["title"] => string(36) ""
      ["author"] => string(22) "-"
      ["user_id"] => string(10) "xenp87gyvk"
      ["read_numbers"] => string(3) "123"
      ["reply_numbers"] => string(4) "3445"
      ["star_numbers"] => string(4) "1322"
      ["cover_url"] => string(41) "/uploads/cover/20180423/5add3c3664db9.jpg"
      ["content"] => string(57) ""
      ["createtime"] => string(11) "04-11 18:52"
    }

6. I tested many times
article keywords can be easily searched out, and the user table of the nickname data, how can not be found,
I try to linux / usr/local/xunsearch/data/db to find index documents, there are user and article documents, what is wrong with my code? I have debugged breakpoints in my UserModel, there is data, and the nickname keyword also exists.
