QUESTION
I need to implement the following (on the backend): a user types a query and gets back hits as well as statistics for the hits. Below is a simplified example.
Suppose the query is Grif
, then the user gets back (random words just for example)
- Griffith
- Griffin
- Grif
- Grift
- Griffins
And frequency + number of documents a certain term occurs in, for example:
- Griffith (freq 10, 3 docs)
- Griffin (freq 17, 9 docs)
- Grif (freq 6, 3 docs)
- Grift (freq 9, 5 docs)
- Griffins (freq 11, 4 docs)
I'm relatively new to Elasticsearch, so I'm not sure where to start to implement something like this. What type of query is the most suitable for this? What can I use to get that kind of statistics? Any other advice will be appreciated too.

- n-gram / partial / search-as-you-type matching
- a way to group the matched keywords by their original form
- a mechanism to reversely look up the document & term frequencies.
- You could start off with a special, n-gram-powered analyzer, as explained in my other answer. There's the original
content
field, plus a multi-field mapping for the said analyzer, plus akeyword
field to aggregate on down the line:
