No results when searching index for emoji

[smnmmnn]

index.search on an input like '😀' yields no results, even if the string has an exact match in the doc. Does this relate to encoding or tokenizing issues?

Yes, it is related to the used "encoder", please try to use another encoder function (takes a string, returns an array of words/terms).

Tried setting a different encoder, but couldn't get that to work: #428
