I beg to differ about the attachments table, in our setup we rely on
customfields and there parameters. We have quite a few tickets that does
not have any attachments.
If you do not write anything in the message body when you create a
ticket (through web-ui or REST), there will be no attachment connected
to that ticket.
Also i did a comparison between mysql/mariadb FULLTEXT index and sphinx,
and it seems that sphinxsearch is able to extract more info than the
mysql FTS. I guess it's about the data processing that sphinx does with
encoding and other things.
Our goal is to include CF's in the fulltext index as well. As far as I
can see right now, there are two ways to do this.
a) Modify the RT simplesearch use an "TicketsIndex" instead of the
Use sphinx to create the TicketsIndex table and modify the collector
query to include both attachment, ticket.subject and customfields in the
the database. (Simple join statements)
b) Create "null" attachments and attach these to tickets that does not
have any current attachments, just to create and relation between ticket
and attachment. The advantage with this is that we do not have to modify
any of the RT code, but of course it adds some rows to the database.
