it should still fix some issue You may use startswith with QuerySet.filter(). Your ORM query should be as:
code :
results = stock.objects.all().filter(symbol__startswith=searchWord)

fixed the issue. Will look into that further I have simple documents with a field called "keywords", which is indexed for text search. The keywords are an array of words and short phrases, like this: , This can be achieved with following setup.
code :
POST your_index
{
  "settings": {
    "analysis": {
      "analyzer": {
        "keyword_analyzer": {
          "type": "custom",
          "filter": [
            "lowercase"
          ],
          "tokenizer": "keyword"
        },
        "shingle_analyzer":{
          "type" : "custom",
          "filter" :["lowercase","shingle_filter"],
          "tokenizer" : "standard"
        }
      },
      "filter": {
        "shingle_filter": {
          "type": "shingle",
          "min_shingle_size": 2,
          "max_shingle_size": 5
        }
      }
    }
  },
  "mappings": {
    "your_type": {
      "properties": {
        "keywords": {
          "type": "string",
          "index_analyzer": "keyword_analyzer",
          "search_analyzer": "shingle_analyzer"
        }
      }
    }
  }
}
PUT your_index/your_type/1
{
  "keywords": ["restaurant manager", "chef", "bus boy"]
}
GET your_index/_search
{
  "query": {
    "match": {
      "keywords": "This restaurant manager is also a good chef"
    }
  }
}

will help you The prefix query applies to not analyzed fields. Check this Term level queries doc For what you are doing you should user a Match Phrase Prefix query Doc here
This is the ES doc, so you must translate that queries to FosElastica queries or just create an array and use it as query.

it fixes the issue If you are trying to simply return a document based on an orderNo, rather than doing a full text search, I would recommend using the "Lookup" API to do so

help you fix your problem You have two options to do this. Either you can use the map function with a regex:
code :
df['TIDY'] = df['INVOICE NUMBER'].map(lambda x: ','.join(re.findall(r'SIN.{11}', x)))
df['TIDY'] = df['INVOICE NUMBER'].str.extractall(r'(SIN.{11})').unstack(fill_value='').apply(','.join, 1)

should help you out The prefix command accepts "value" not "prefix". Also the "boost" value is numeric type, so it shouldn't be enclosed in quotes.
So it should be:
code :
{"prefix":{"title":{"value":"of","boost":1.0}}}
{"prefix":{"title":{"prefix":"of","boost":"1.0"}}}
