Hi,
I was trying Filtered query (default search type) to fetch first 8k out of
approx 170k matched records. I noticed that on an average query took around
500ms (response.getTookInMillis()). But, when I tried 4 concurrent searches
over same dataset (in ideal scenario dataset will be different), I noticed
that the performance degraded and each query took more than 1sec on
average. Is this degradation in search response expected?
I still haven't tried with scroll and scan as order is not important, but,
curious to know if anything wrong with query or the way I executed.
I am executing search on single index having around 850k docs (each doc
contains around 5 fields), with 1g allocated to ES and using java node
client to execute searches. Following is the query JSON:
{
"from" : 0,
"size" : 8000,
"query" : {
"filtered" : {
"query" : {
"match_all" : { }
},
"filter" : {
"and" : {
"filters" : [ {
"term" : {
"details" : "Holiday"
}
}, {
"range" : {
"createdOn" : {
"from" : 0,
"to" : 1429260645351,
"include_lower" : true,
"include_upper" : true
}
}
}, {
"terms" : {
"priority" : [ 1, 2 ]
}
} ]
}
}
}
},
