Elasticsearch 400 error when searching multiple words

[cpebble]

Describe the bug
We're trying to index and search through several internal knowledge bases. In context we have search-dropbox which uses the Elastic dropbox connector client(self-hosted) and search-sphinx which is indexed through a custom script.

Building the front-end with react and search-ui got us far <3
However, we have run into an issue when searching the Dropbox index. We can easily search for one word, however if we add a second word we get http 400. I.e. "Docker" works, but "Docker swarm" does not.

Specifically we get: search_phase_execution_exception which points to this error: failed to create query: field:[name] was indexed without position data; cannot run PhraseQuery.

And our QueryConfig is this:

{
  "searchQuery": {
    "search_fields": {
      "name": {
        "weight": 3
      },
      "body": {
        "weight": 5
      }
    },
    "result_fields": {
      "name": {
      },
      "body": {
        "snippet": { "size": 250, "fallback": true },
        "raw": {}
      },
      "file_path": {}
    },
  },
  "autocompleteQuery": {},
  "apiConnector": this.connector,
  "alwaysSearchOnInitialLoad": true
}

To Reproduce
Steps to reproduce the behavior:

1. Index a Dropbox target using Elastic Connector Clients
2. Search this target

Expected behavior
Search results

Which backends and packages are you using:
Backend: Elasticsearch
Packages: Search-ui, Search-ui-elastic-connector, react-search-ui

Hey
Thank you for your question, the issue is unlikely on the serch-ui side. Probably it's related to the field mapping, maybe using some no position data like "index_options": "docs"
doc

@yansavitski I did look at that, however the index(in Kibana) at least looks like this:

      "name": {
        "type": "text",
        "fields": {
        ....
        },
        "index_options": "freqs",
        "analyzer": "iq_text_base"
    }

Unless i'm completely off-base this should be right, right?

Hey
index_options: freqs Can't be use with match_phrase search with multiple words

You can play with index_options parameter by following the code bellow:
`PUT /my_index_no_positions
{
"mappings": {
"properties": {
"content": {
"type": "text",
"index_options": "freqs" // No positions data
}
}
}
}

POST /my_index_no_positions/_doc/1
{
"content": "This is a sample document to demonstrate match_phrase functionality."
}

POST /my_index_no_positions/_doc/2
{
"content": "Elasticsearch allows powerful full-text search capabilities."
}

GET /my_index_no_positions/_search
{
"query": {
"match_phrase": {
"content": "full-text search"
}
}
}`
