Search with criteria returns empty data

[bondar-aleksandr]

Search returns empty *SearchData, regardless of criteria used

Code example:

criteria := &imap.SearchCriteria{}
criteria.Flag = []imap.Flag{imap.FlagSeen}
criteria.Header = []imap.SearchCriteriaHeaderField{
  {Key: "FROM", Value: appConfig.From[0]},
}
fmt.Println(criteria)
searchData, err := Client.Search(criteria, nil).Wait()
fmt.Println(searchData)

Output:

&{[] [] 0001-01-01 00:00:00 +0000 UTC 0001-01-01 00:00:00 +0000 UTC 0001-01-01 00:00:00 +0000 UTC 0001-01-01 00:00:00 +0000 UTC [{FROM [e-mail]}] [] [] [\Seen] [] 0 0 [] [] <nil>}
&{ false 0 0 0 0}

In version 1.2.1 everything works just fine

Can you share debug logs?

[bondar-aleksandr]

I don't have access to server side (I use "imap.ukr.net"). What do you mean by debug logs?

[Simon Ser]

I mean ClientOptions.DebugWriter set to os.Stderr or something

Sure, here it is:

Hm, the server returns 0 results, and the command looks good to me. Can you try getting go-imap v1 debug logs as well so that we can compare?

[bondar-aleksandr]

I found the problem. First of all, there were no messages corresponding to search criteria in mailbox. As soon as I fixed that, I saw the search result. What guided me wrong, was the fact that I counted on .Count field in SearchData struct in search.go

type SearchData struct {
	All SeqSet

	// requires IMAP4rev2 or ESEARCH
	UID   bool
	Min   uint32
	Max   uint32
	Count uint32

	// requires CONDSTORE
	ModSeq uint64
}

But .Count doesn't changes regardless of how many items are in .All

[bondar-aleksandr]

Sorry for that :(

[Simon Ser]

Yeah, the count requires additional extensions as hinted in the comment above.
