Subject: fts: Add reason_code=fts:index and fts:lookup
X-Git-Tag: 2.3.18~326
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=88c2ee58f1027ee00329cd66d36d894230fd4ec0;p=thirdparty%2Fdovecot%2Fcore.git

fts: Add reason_code=fts:index and fts:lookup

Note that fts:index won't be used for email opening events, because the
emails are already opened by the indexer precache searching code due to
wanted_fields.
