I noticed that currently it is not possible to use the server side search ( don’t know the correct name). The dovecot server i have has a solr instance for Full text search and using imap webclients like nextcloud or rainloop it works perfectly. However when do do a search using z-push (and the windows 10 client, and also using the native android mail app) i don’t get any results.

Solr however does give the result but somehow z-push fails with the following error in the z-push-error log.:

09/08/2018 21:21:54 [16487] [WARN] [jurgen] /usr/share/z-push/lib/request/search.php:462 Invalid argument supplied for foreach() (2)

In the solr log i see the search being done and giving result to dovecot:
