How do I search files include two words?

[scc02]

vim.keymap.set("n", "<leader>fg", function()
  local word1 = vim.fn.input("Enter first word: ")
  if word1 == "" then return end
  local word2 = vim.fn.input("Enter second word: ")
  if word2 == "" then return end

  local cmd = string.format(
    "rg --hidden --iglob !.git -l %s | xargs -I {} rg --no-heading --line-number --column -e %s {}",
    vim.fn.shellescape(word1),
    vim.fn.shellescape(word2)
  )

  require("fzf-lua").fzf_exec(cmd )
end, { desc = "Live grep for two words" })

I have tried this; I can search, but I cannot open the entry in result.

1. you didn't provide actions for your keys (enter, ctrl-s...)

fzf_exec(cmd, { actions = { enter = function() ... end })

Use :helpgrep actions.file_edit, you will find more builtin actions.

2. your line format didn't provide a standard format that fzf-lua actions can parse. (so the builtin actions won't work).
   (And since you didn't provide a filename each line: it's also impossible to get where the file is, since fzf-lua didn't store entry internally, they are streaming in another fzf process... if you want to hide filename? you can use fzf_opts.["--with-nth"], checkout man fzf for details about that).

3. I personally think there's some (maybe) alternatives to your workflow...

• use fzf-lua.live_grep, input the first word, then ctrl-g to switch to fuzzy match and input the second word. (If you just don't like fuzzy match, set fzf_opts['--exact'] = true.
• Or there's a similar question recently, Fuzzy find among projects lines, and use globs to filter filtes #1940.

  if word1 == "" then return end

  local word2 = vim.fn.input("Enter second word: ")
  if word2 == "" then return end

  local cmd = string.format(
    "rg --hidden --iglob !.git --files-with-matches %s | xargs rg --with-filename --column --line-number --no-heading -e %s",
    vim.fn.shellescape(word1),
    vim.fn.shellescape(word2) 
  )

  require("fzf-lua").fzf_exec(cmd, {
    actions = {
      -- 当用户按 Enter 选择结果时触发
      ["enter"] = function(selected, opts)
        print("Selected: " .. selected[1])
        require("fzf-lua").actions.file_edit_or_qf(selected, opts)
      end,
    },
    previewer = "builtin",                
  })
end, { desc = "Live grep for two words" }) 

works now

Why don’t you use grep (or live grep, depending which mode you wanna start) with a regex for the two words:

require("fzf-lua").grep(({ search = string.format("(%s|%s)", word1, word2), no_esc=true })

[scc02]

Not either-or, but containing both words at the same time.

[nenahp]

require("fzf-lua").grep({ search = string.format("(?=.*%s)(?=.*%s)", 'abc', 'def'), no_esc=true, rg_opts = [[--pcre2 --column --line-number --no-heading --color=always --sm
art-case --max-columns=4096 -e]] })

I’m sure there’s a regex for AND.

[scc02]

require("fzf-lua").grep({ search = string.format("(?=.*%s)(?=.*%s)", 'abc', 'def'), no_esc=true, rg_opts = [[--pcre2 --column --line-number --no-heading --color=always --sm
art-case --max-columns=4096 -e]] })

Can we fix this? not just slient = true

most likely no, this is from the vim regex engine trying to match the previewer text but vim.regex isn’t as feature rich as PCRE2.
