如何修改Neovim Telescope live grep的预览条目上限？

在Neovim的Telescope live grep中搜索关键词，结果显示该关键词在多文件中共出现997次，但无法浏览全部匹配结果——grep窗口仅能循环显示约100条预览条目。需要快速查看所有匹配内容，却受限于预览窗口的循环范围，请问Telescope是否有对应的配置选项？

我的默认Telescope配置 #

local options = {
  defaults = {
    vimgrep_arguments = {
      "rg",
      "-L",
      "--color=never",
      "--no-heading",
      "--with-filename",
      "--line-number",
      "--column",
      "--smart-case",
    },
    prompt_prefix = "   ",
    selection_caret = "  ",
    entry_prefix = "  ",
    initial_mode = "insert",
    selection_strategy = "reset",
    sorting_strategy = "ascending",
    layout_strategy = "horizontal",
    layout_config = {
      horizontal = {
        prompt_position = "top",
        preview_width = 0.55,
        results_width = 0.8,
      },
      vertical = {
        mirror = false,
      },
      width = 0.87,
      height = 0.80,
      preview_cutoff = 120,
    },
    file_sorter = require("telescope.sorters").get_fuzzy_file,
    file_ignore_patterns = { "node_modules" },
    generic_sorter = require("telescope.sorters").get_generic_fuzzy_sorter,
    path_display = { "truncate" },
    winblend = 0,
    border = {},
    borderchars = { "─", "│", "─", "│", "╭", "╮", "╯", "╰" },
    color_devicons = true,
    set_env = { ["COLORTERM"] = "truecolor" }, -- default = nil,
    file_previewer = require("telescope.previewers").vim_buffer_cat.new,
    grep_previewer = require("telescope.previewers").vim_buffer_vimgrep.new,
    qflist_previewer = require("telescope.previewers").vim_buffer_qflist.new,
    -- Developer configurations: Not meant for general override
    buffer_previewer_maker = require("telescope.previewers").buffer_previewer_maker,
    mappings = {
      n = { ["q"] = require("telescope.actions").close },
    },
  },

  extensions_list = { "themes", "terms" },
}

return options

我尝试过的无效设置 #

preview:
  - check_mime_type
  - filesize_limit
  - timeout
  - hook(s)
  - treesitter
  - msg_bg_fillchar
  - hide_on_startup
  - ls_short

解决方案 #

1. 调整Telescope全局最大结果数限制 #

问题根源是Telescope默认将搜索结果数量限制为100条，你可以在defaults配置中添加max_results参数，设置一个足够大的数值（比如1000）来显示全部结果：

修改你的配置文件，在defaults块中加入：

max_results = 1000,

修改后的defaults部分示例：

defaults = {
  -- 原有配置...
  max_results = 1000,
  -- 原有配置...
}

2. 将结果导入Quickfix列表浏览 #

如果不想修改全局配置，也可以在Telescope的live grep窗口中，按下<C-q>（默认快捷键）将所有匹配结果导入到Quickfix列表，然后执行:copen命令打开Quickfix窗口，就能在其中浏览全部997条匹配内容。
