Hi,

I have some troubles with searching and could not find an answer yet. The search term is „istop“ in the subject. The client was SOGo.

We run the recent dovecot, with solr backend and milder with zlib compression.

Searching for all small letters „istop“ shows up no hit.

Searching with a capital „S“ „iStop“ shows all messages back 10 years ago.

Sprachig for „istopmotion“ all messages show up, wether the subject contains caps or non caps at all.

I did a telnet to our dovecot and searched by hand for all three terms:

8 search Subject istop

• SEARCH 8 OK Search completed (0.025 + 0.000 + 0.022 secs).

9 search subject iStop

• SEARCH 544 604 654 662 910 1394 1471 1474 5493 9 OK Search completed (0.028 + 0.000 + 0.023 secs).

10 search subject istopmotion

• SEARCH 544 604 654 662 910 1471 1472 1474 5493 10 OK Search completed (0.027 + 0.000 + 0.023 secs).

  Any hints or suggestion is welcome as I m very confused and lost. Thanks and regards . Götz
