Why elasticsearch defined default analyzer doesn't work?

I put content in elasticsearch without define the index setting. It seems
by default elasticsearch isn't using the default analyzer I defined in

index.analysis.analyzer.default.type: ik

If I request: http://localhost:9200/useridx/_search?q=Lin

it doesn't using the default analyzer

Could some one help me make the default analyzer ik when querying?
