How can I query my index to suggest phrases that complete the user's query? I'd like a query similar to
match_phrase_prefix , except instead of retrieving the entire doc it returns n-grams from the doc fields that completes the phrase?
None of the suggesters seem to fit my use-case, where
completion suggester requires that suggestions be indexed explicity, and
phrase suggester seems to suggest spelling error fixes instead of phrase completions.
