You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: find.go
    path of file: ./repos/restic/cmd/restic
    
    the code of the file until where you have to start completion: package main

import (
	"context"

	"github.com/restic/restic/internal/restic"
	"github.com/spf13/pflag"
)

// initMultiSnapshotFilter is used for commands that work on multiple snapshots
// MUST be combined with restic.FindFilteredSnapshots or FindFilteredSnapshots

	hostShorthand := "H"
	if !addHostShorthand {
		hostShorthand = ""
	}
	flags.StringArrayVarP(&filt.Hosts, "host", hostShorthand, nil, "only consider snapshots for this `host` (can be specified multiple times)")
	flags.Var(&filt.Tags, "tag", "o
    
func FindFilteredSnapshots(ctx context.Context, be restic.Lister, loader restic.LoaderUnpacked, f *restic.SnapshotFilter, snapshotIDs []string) <-chan *restic.Snapshot {
	out := make(chan *restic.Snapshot)
	go func() {
		defer close(out)
		be, err := restic.MemorizeList(ctx, be, restic.SnapshotFile)
		if err != nil {
			Warnf("could not load snapshots: %v\n", err)
			return
