Atlas search not working properly when searching for a string with space in it

MongoDB Atlas Atlas Search
#1

Hi, I’m working on a feature in which we need to search by name in our database. The search works fine for single word queries, but when I input a string with spaces in it (2 or more words), the results are not accurate, because it returns different documents which match only one of the words that I inputted. From what I have read on a similar post on this forum, it might be a tokenization issue and the person which fixed it made a fix which works for exact matches, here I need an autocomplete solution for this issue.

Hi @Dan_Muntean1! Can you share your index definition, an example query and sample document?

Hi, here is my index:

{
  "mappings": {
    "dynamic": true,
    "fields": {
      "groupTag": {
        "type": "autocomplete"
      },
      "name": {
        "type": "autocomplete"
      }
    }
  }
}

Here is my document:

{
  "_id": {
    "$oid": "63e4f8a261f74736f0fcc8b6"
  },
  "_v": 4,
  "groupTag": "T-2",
  "createdAt": {
    "$date": {
      "$numberLong": "1675950242663"
    }
  },
  "updatedAt": {
    "$date": {
      "$numberLong": "1676022397735"
    }
  },
  "name": "Dan test group",
}

And if I search for the name “Dan test group”, the search feature returns me other documents which contains in the name field any of the words “Dan”, “test”, “group”, and I end getting information that I didn’t search for. I need the search to return documents which name contains the entire string that I typed (“Dan test group”).
