for this i searched in google they told to add
this line in elasticsearch.yml fixed 200 20000

but still its showing that error

note:im using mac
using local ip

Hi @manopmk,

this sounds like Elasticsearch does not have enough resources to completely answer the query. Increasing the search threadpool size is a measure that might help, but like all performance parameters it is highly dependent on the runtime environment. The Elasticsearch log output might give some indication about the reason for the 10 failed shards.

Thank you buddy
