I am using Elasticsearch 5.5.2. I have the below mapping and the documents

Mapping --  
PUT /testindex/  
{  
"mappings": {  
"testtype": {  
"properties": {  
"city": {  
"type": "text"  
}  
}  
}  
}  
}

Documents --

First one --  
"\_source": {  
"city": "a"  
}

Second one --  
"\_source": {  
"city": "ab"  
}  
And Third one --  
"\_source": {  
"city": "abc"  
}

When I try the below, I am NOT getting any suggestions

POST /testindex/testtype/\_search  
{  
"suggest": {  
"my\_suggest": {  
"text": "a",  
"term": {  
"field": "city",  
"min\_word\_length": 1  
}  
}  
}  
}

As per my understanding of the documentation of the term suggester, I am expecting 'ab' as the suggested term for the above query. But I am getting zero suggestions as the result for the above query. Can someone please clarify where I am wrong?

In the below query, for the suggest text 'ab', I am getting 'abc' as the suggested term

The query with 'ab' as the suggest term is

POST /testindex/testtype/\_search  
{  
"suggest": {  
"my\_suggest": {  
"text": "ab",  
"term": {  
"field": "city",  
"min\_word\_length": 1  
}  
}  
}  
}

The result I am getting is  
"options": [  
{  
"text": "abc",  
"score": 0.5,  
"freq": 1  
}  
]

When I am getting 'abc' as the suggested term for the suggest text 'ab', why I am NOT getting 'ab' as the suggested term for the suggest text 'a', though I have set the property 'min\_word\_length' to 1.

Please clarify.

Thank you very much.
