I'm trying to say if the event has '%webinar%','%network%' in the name include it "if" the date is after the 01-04-2015. I cant use "or" on a separate line as it ignores the date. Any help appreciated.
select 
    ,fsa.eventid
    ,sev.EventStart
    from
    event sev
    on 
    sev.eventId = fsa.eventid
    where sev.SNAP_EventStart >= '2015-04-01'
    and eventidname in ('%webinar%','%network%')
