Add Algolia synonyms just by posting in Slack
You notice shoppers type sneakers when your data says trainers, and you want that fixed before you forget. Post the synonym in your search channel and Notis saves it to Algolia, so the fix lands while the insight is fresh.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action
Save Synonym
Tool to add or update a synonym in the specified index. use when you need programmatic upsert of search synonyms after index creation.
Why this helps
Search vocabulary gaps get spotted in conversation and then lost, because logging into Algolia to add a synonym never feels urgent enough in the moment.
- Capture a synonym the instant you notice a vocabulary gap.
- Upserts cleanly, so posting again just refines the existing synonym.
- Keeps search matching real words your users type.
Setup
Build it in a few focused steps.
- 1Connect Slack and Algolia to Notis once from the portal.
- 2Create a new automation in the portal Automations screen.
- 3Describe the outcome plainly, for example: when I post a synonym pair in this channel, save it to my Algolia index.
- 4Choose the Slack channel message trigger, pick the channel, and set where Notis reports runs.
- 5Post a test synonym and confirm it shows up in Algolia.
Questions about this workflow
What format should the message use?
Just write the terms that should be treated as equivalent in plain language. Notis interprets the message and saves the synonym for you.
Does reposting create duplicates?
No. Saving a synonym is an upsert, so an updated post refines the existing entry rather than creating a second one.
