Should term vector query remain on 'spelling' field ?

[romainruaud]

This is a question.

When doing a search, we first process a termVector query to know if we have the terms in index.

This termVector query is processed on the spelling field.

=> An attribute configured with used_in_spellcheck=false will NOT be copied into the spelling field.

Let's say we have a "color" attribute with the value "blue" and set as used_in_spellcheck=false.

When doing a search on blue, here is the termVector query :

{"doc":{"spelling":"blue"}}

=> This term vector will return no matches ! Because the term blue is NOT on the spelling field.

=> We will process a fuzzy search instead of an exact one. And the fuzzy query is processed only on spelling field => no results !

=> With the current config, this is mandatory to set is_used_in_spellcheck=true if we want to have search results for a given field.

So my question is : why do we not process the term Vector query on the search field ? It would contain the blue value on the example below.

Thank you for your answer @afoucret

It allows to trigger the fuzzy search even when there is mispelling in description by example.
So it is a design choice.
