Filter and Query same taking some time

Elastic Stack Elasticsearch
5

My app is index heavy so we are putting a lot of documents and also
searching in mean while (using it as datastore).
Most of the time the threads are stuck on merge if segments. Can you
suggest us some optimizations ?

Thanks ,

Yeah 100000 documents is not that much!
Not sure if you can notice a difference here as probably everything could
be loaded in file system cache.

I have 100,000 documents which are similar. In response I am getting the
whole document not just Id.
I am executing the query multiple times.

You probably won't see any difference the first time you execute it
unless you are using warmers.
With a second query, you should see the difference.

How many documents you have in your dataset?

Hi,

I had implemented ES search query for all our use cases but when i came
to know that some of our use cases can be solved by filters I implemented
that but I dont see any gain (in response time) in filters. My search
queries are

  1. Filter

{
"size" : 100,
"query" : {
"match_all" : { }
},
"filter" : {
"bool" : {
"must" : {
"term" : {
"color" : "red"
}
}
}
},
"version" : true
}

  1. Query

{
"size" : 100,
"query" : {
"bool" : {
"must" : {
"match" : {
"color" : {
"query" : "red",
"type" : "boolean",
"operator" : "AND"
}
}
}
}
},
"version" : true
}

By default the term query should be cached but I dont see a performance
gain.
Do i need to change some parameter also ?
I am using ES 0.90.1 and with 16Gb of heap space given to ES.

Thanks,
Arjit
