now i found that the problem maybe caused by the index
because only logstash(2018.04.14) and logstash(2018.04.14) only they will report mistake
and 4.11 4.12 success . but they have nothing different

can search data?

yes ,i test everything ,like search , open and close ,it just can't be indexed

try snapshot and restore
