@dzango-roshan You need to create your own collection in typesense (with marking facets in it) and point that collection in this integration

Do you mean manually create, like: `curl "${TYPESENSE_HOST}/collections" \ -X POST \ -H "Content-Type: application/json" \ -H "X-TYPESENSE-API-KEY: ${TYPESENSE_API_KEY}" -d '{ "name": "books", "fields": [ {"name": "title", "type": "string" }, {"name": "authors", "type": "string[]", "facet": true },

      {"name": "publication_year", "type": "int32", "facet": true },
      {"name": "ratings_count", "type": "int32" },
      {"name": "average_rating", "type": "float" }       
    ],
    "default_sorting_field": "ratings_count"
  }'

Then run this tool with--typesense-collection=books` ?

I got an err: ✖ Create a new Typesense Collection → Request failed with HTTP code 409 | Server said: A collection with namebooksalready exists.

Hey @harisarang, I'm having the same issue as @yijia99. I tried to create a collection manually to enable the facets and then tried to run typesense-mongodb and I'm getting the following error:

npx typesense-mongodb \
    --mongo-collection=books \
    --mongo-database=test \
    --typesense-collection=books \
    --mongo-url=mongodb://localhost:27017 \
    --typesense-url=http://localhost:8108 \
    --typesense-api-key=xyz

@yijia99 were you able to solve it?

Hi @jzrchilel My tmp solution is to skip creating collection anyway, e.g: lib/main.js

` {

            title: "Create a new Typesense Collection",

            task: () => typesense.createCollection(options.typesenseCollectionName),

            skip: () => 

            // skip anyway

            true

                ? "Found an existing collection skipping create collection"

                : undefined,
        },

`

But this tool failed again when I process a 5k+ documents mongoDB collection. Same as: https://github.com/typesense/typesense-mongodb/issues/11

So finally I had to write my own connector scripts.

https://github.com/typesense/typesense-mongodb/blob/de96e815eabdf41f9ee8498dcde0c0f41727007a/src/main.ts#L108-L115

These sections of code cause the issue. In a fresh install of mongodb and typesense, no documents exist. As a result, line 93 returns 0 and the task Create a new Typesense Collection will not be skipped. To work around this issue, we can follow the steps below:

1. Create your own collection in typesense.
2. Index at least one document into the collection created in step 1.

If you only attempt step 1, you still encounter the error. However, if you try with both steps, you'll encounter a new error A document with id xxx already exists..

Finally, I changed line 93 to result.name === collectionName which resolved both errors.
