Note: Any issue that does not follow below template will be closed without consideration. You may remove this line when filing issue.

What were you trying to achieve?
I have 3 issues 1) Indexing 1M+ docs gives below error 2) how to do fuzzy search from UI. I am trying to search for "earning", I would like to match it to "Earnings" (note capitalization, plural) and have it highlighted 3)any way to search for synonyms for eg: keyword: increase should also match 'rise' (I can supply pre-defined vocabulary as needed)

What action did you take?
Call index endpoint using python

    headers = {"Content-type": "application/json", "Authorization": "Basic " + bas64encoded_creds}
    index = "stockbuddy"
    zinc_host = "http://dell.local:4080"
    zinc_url = zinc_host + "/api/" + index + "/_doc"
    
    for doc in tqdm(docs):
        res = requests.put(zinc_url, headers=headers, data=json.dumps(doc))
        print(res.text)

sample doc:
docs = [{"symbol": "A", "story": "Agilent (A) Down 2.2% Since Last Earnings Report: Can It Rebound?", "source": "Zacks", "story_datetime": "2023-06-22T11:30:00"}]

What action/response/output did you expect?
