I'm running into an issue with this Algolia/InstantSearch to Typesense adaptation. I have a Typesense field setup like this:

[
    'name' => 'attributes\.*',
    'type' => 'auto',
    'optional' => true,
    'facet' => true
]

This seems to work fine. It indexes all the flattened attribute fields with dot-notation. The issue is that not every document has all the attribute fields, which makes the InstantSearch fail.

Error: 404 - Could not find a facet field named `attributes.operating-system` in the schema.

Is this a bug in the InstantSearch adapter, or am I doing something wrong?

Could you GET the collection and double check that that attribute shows up in the schema?

it's an "auto" type attribute defined as stated above.

There is a typo in the name in the schema. It should be

attributes\..*

oh, ok! an extra dot. thank you, I will try this!

What we want is to match any field that begins with

attributes.

-- since the dot is a special character in regexp, we have to use a backslash to escape it, like this

\.

. Then we want to match any number of characters after that, so we use

.*

-- putting those two together:

attributes\..*

oh yea, of course, I get it now! thank you for the great support! and it worked! Algolia OUT -> Typesense IN 🙂

🎉 happy to help
