Dovecot 2.2.34 FTS-SOLR = inconsistent results

5 Mar 2018


      Hello,
I'm trying to figure why I have inconsistent results with my fts-solr
powered search:
My test is to find the string "am5oocobey9hait5Wiex8yohgoob9thu" in the
3 emails containing it that I sent to myself:

Directly on the server:
doveadm search -u username text am5oocobey9hait5Wiex8yohgoob9thu
e2c58a3093235153110800003ea484a8 7937
e2c58a3093235153110800003ea484a8 7938
e0c58a3093235153110800003ea484a8 36479
e0c58a3093235153110800003ea484a8 36480
e0c58a3093235153110800003ea484a8 36481

RoundCube webmail:
0 Result

On the server with "telnet localhost imap" (2 identical searches):
[snip...]

No error in solr.log and it seems to be indexing okay:

I would be very grateful if someone can point me where my error is, as
I've been on this problem for weeks :(
Thanks,
