Slack provides an
in: search modifier to narrow the scope of
results to a given channel. Further, multiple
in: modifiers will filter
results to a set of channels.
The problem I was trying to solve was to search within a large set of channels; too many to bother typing into a single search query.
All the channel names followed a pattern so I was hoping I could use a wildcard
in:tech-guild-* but alas no.
However it turns out the
in: modifier can act on a custom channel section, and
I happened to have a “Tech Guilds” section including all the relevant channels.
in:Tech Guilds was the filter I needed.
