Union parameter not passed in multi-search queries

[ragusa87]

I tried to use multi-search with "Union" type on typesense==1.1.1.

Snippet:

        for model, collection in model_and_collection:
            query.append(
                {
                    "collection": collection.schema_name,
                    "query_by": collection.query_by_fields,
                    "q": q,
                }
            )
        results = client.multi_search.perform(
            {
                "union": True,
                "searches": query,
            }, {
                "per_page": self.paginate_by,
                "page": page_number,
            }
        )

But I realized that the result doesn't consider the union parameter. I have as many results as collection, and not a "grouped" hits results as expected.

After some investigation, I found out that the parameter "union" is not passed to the query.

    def perform(
        self,
        search_queries: MultiSearchRequestSchema,
        common_params: typing.Union[MultiSearchCommonParameters, None] = None,
    ) -> MultiSearchResponse:
        """
        Perform a multi-search operation.

        This method allows executing multiple search queries in a single API call.
        It processes the search parameters, sends the request to the Typesense API,
        and returns the multi-search response.

        Args:
            search_queries (MultiSearchRequestSchema):
                A dictionary containing the list of search queries to perform.
                The dictionary should have a 'searches' key with a list of search
                    parameter dictionaries.
            common_params (Union[MultiSearchCommonParameters, None], optional):
                Common parameters to apply to all search queries. Defaults to None.

        Returns:
            MultiSearchResponse:
                The response from the multi-search operation, containing
                    the results of all search queries.
        """
        stringified_search_params = [
            stringify_search_params(search_params)
            for search_params in search_queries.get("searches")
        ]
        search_body = {"searches": stringified_search_params}

        response: MultiSearchResponse = self.api_call.post(
            MultiSearch.resource_path,
            body=search_body,
            params=common_params,
            as_json=True,
            entity_type=MultiSearchResponse,
        )
        return response

In the code above, you can see that "union" is not put into search_body.

Adding a line like that fixed it:

search_body["union"] = search_queries.get('union', False)

I will try to submit a MR about it.

Hello @tharropoulos ,

The fix #96 has been merged, thanks a lot for that. Do you have any idea when I could expect a release to integrate it?

Thanks for your answer!

In the coming weeks, we'll release our v30 GA build for the main server. We'll roll out client updates alongside with it, so keep in an eye out in the coming days!
