Autocomplete Substring Match

Vote:

At the moment is only able to prefix match

As per above

"The autocomplete functionality only works from the beginning of a phrase; the search term must begin with the first word in the autocomplete phrase."

var autoCompletePhrases = await Client.Statistics().AutocompleteAsync(queryterm, count);

Is there anyway to substring match

so if my auto complete term is "one two three"

The result is returned if I start with "one".

If I pass "two" it does not return anything.

Instead of using AutocompleteAsync, you can implement your own autocomplete logic using a standard search query with a wildcard or n-gram analyzer:

var results = searchClient
    .Search<YourContentType>()
    .Filter(x => x.SearchTitle.MatchWildcard($"*{queryTerm}*"))
    .Take(10)
    .GetResult();
