Query several Algolia indices with one Slack message
When the answer could live in any one of your indices, running three separate searches is exhausting. Send Notis a single DM and it queries all the indices you care about at once and brings back one tidy reply.
Trigger
Direct Message Received
Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.
Action
Search Multiple Indices
Tool to perform searches across multiple indices in a single call. use when you need to batch multiple index queries into one api request.
Why this helps
You are not sure whether the record you need is in products, docs, or contacts, so you run the same query three times and stitch the results together in your head.
- One DM searches every index you specify in a single request.
- See results side by side instead of running lookups one at a time.
- Cuts the mental overhead of remembering where each thing lives.
Setup
Build it in a few focused steps.
- 1Connect Slack and Algolia to Notis once from the portal.
- 2Ask Notis for your portal link and open Automations to create a new one.
- 3Write a plain-language instruction, for example: when I DM you a term, search these indices together and reply with the best matches from each.
- 4Select the Slack direct message trigger and choose the channel for run reports.
- 5DM yourself a real query and confirm results from each index come back together.
Questions about this workflow
How does Notis know which indices to search?
You list them once in the plain-language instruction. Notis remembers that set and searches all of them each time you ask.
Can I still search just one index sometimes?
Yes. Mention the single index by name in your DM and Notis will narrow the search to that one for that request.
