I have a simple database of articles (title + body):

```auto
"mappings": {
    "properties": {
        "title": {
            "type": "text",
            "analyzer": "..."
        },
        "body": {
            "type": "text",
            "analyzer": "..."
        },
    }
}

```

When searching I use a multi\_match query to boost the title field:

```auto
"query": {
    "multi_match": {
        "query": "...",
        "fields": ["title^1.2", "body"],
    }
}

```

I would like to add semantic search here (hybrid).  
What is the best way to implement this behavior using neural search? I’ve read the [tutorial](https://opensearch.org/docs/latest/search-plugins/neural-search-tutorial/), but still can’t get what to do with the second field. If I calculate two vectors (title\_embedding, body\_embedding) how can I combine them in a neural query?

One more question: without boosting. Is there any way to concatenate two fields for ingest pipeline to avoid making another one in the mappings section? Something like this:

```auto
"mappings": {
    "properties": {
        "title": {},
        "body": {},
       "title_body_embedding": {} // vector of title + ' ' + body
    }
}

```
