Hi ES Users,
Is there any way I can hide some of the common fields which are being
returned as a response by ES.
e.g if I get the response as below:
*{
took: 74
timed_out: false
_shards: {
total: 15
successful: 15
failed: 0
}
hits: {
total: 24
max_score: 0.15932977
hits: [
{
_index: prashant
Is there any way around for this case?

Hi ES Users,
I have indexed a large sample of data to ES. Now I am running the cluster
query to categorize the data on the basis of Content. But I don't want the
Content field to be returned as ES response i.e. I want only the Cluster
labels and ID's so is there any way around this scenario?

Hi ES Users,
Is there any specific query which can be used to fetch the records of one
particular label.
e.g.: Using _search_with_clusters I got response as
*{id: 3
score: 0.9494177601684511
label: Nokia
phrases: [
Nokia
]
documents: [
XQqcFFOlRDm7-FfIVz-U1A
rXJT_mKpQWKB9x9Zs2ipJw
]
}
{
id: 4
As the cluster labels will be known after performing one search query.
So if my search query is:
{
search_request: {
Content
],
query: {
match: {
_all: mobile
}
},
size: 1000,
from:0
},
query_hint: mobile,
field_mapping: {
content: [
Hi Dawid,

Sorry If I have asked a question which is not relevant to forum.
I explored the Project repository already and what I got for Web App is war
file at http://project.carrot2.org/download.html
http://project.carrot2.org/download.html
But I was just thinking if there is any source code(html
Yes I checked this link as well till the web app. Which is having the code
altogether as java code.
What I thought is if we are doing any search just through json request in
html pages so it is storing some info as cookies in client side and through
HTML pages only the results are being retrieved
Yes that's what I was looking for throughout the source code and not able to
pullout.
What I was interested to know through the source code is How data is
handled on web after firing the first query(which returns the set of cluster
labels and on user event we can navigate through various labels)
It could be a silly question but just wanted to know that can we integrate
the carrot2 web application with our Elasticsearch instance?

Hi Dawid,
If I understood correctly wrt ES,
1) Once we send the docs to ES it will index the data (Clustering i.e.
assign cluster labels will not happen at this time). And only the documents
will be stored to ES.
2) Once we send the search query it will fetch the records, and on top of
that
Hi Dawid,
On-demand and real time happens on a subset of documents from the
index and should return clusters
within a reasonable amount of time (so that users can interact with
the system).
This means that there is no concept like real time and on demand in ES. Only
after firing the search
Hi Clinton/gkwelding,
Any suggestion to overcome this issue as I tried by increasing the heap size
and still getting the same error.
Below are the call logs for the issue:

MAX_OPEN_FILES and MAX_MAP_COUNT are not being set explicitly, so having
default value only i.e. 65535.
And still its crashing with same error :(

Hi Mark,
I read some where that there are clustering like real time and on demand so
was keen to know about that.
I have one more concern that might be the silly one but still wanted to know
about that *whether clustering happens at the time when we are indexing the
data to ES or it happens
The indexing happens as soon as you post a document to ES, not as you query
it.
ES will automatically replicate the document (depending on your setup) at
the same time.
This is fine for indexing.
But what happens exactly wrt clustering. Clustering means I wanted to know
like I submitted one docs
There are two scenario.
1) I am submitting the documents to ES for indexing.
2) I am executing a search query using cluster plugin.
Just to elaborate through example.
*Step 1:
*curl -xPOST 'http://192.168.0.179:9200/prashant' -d
{
mappings: {
emp: {
properties: {
One more observation in above scenario.
1) The records returned by the mobile is 287 so if I set the size (in
query) as 287 it is working fine but in case of =287 it is throwing the
exception.
2) The records returned by the samsung is 191 so if I set the size as
191 it is working fine also in
I tried increasing the heap value by 2GB as well by ES_MAX_MEM: 2g but it
gave the same error.

I am using the bulk API for indexing the data. And also refresh parameter is

So what could be the issue for that exception.

Hi All,
I am using head plugin to access the elastic search through GUI and cluster
plugin to cluster the data.
So is there anyway I can display any particular field in GUI of
elasticsearch.
For ex:
If my query is
*{
search_request: {
fields: [
Content
],
query: {
match:
So it means that all the classification has to be done prior, on the basis of
user defined scenario.
And automatically this feature is not supported either through carrot or
Lingo3g. Like we have the feature of word-delimiter, hunspell filter etc.

Hi All,
Is there any way to measure end-to-end response time for a query in elastic

That is the time taken from the time query is executed and the result is
shown on the ES UI.
And what does took parameter means in response ouput?

Searching for Laptop will automatically give result for Dell, Sony, HP,

For that I have installed Carrot2 and Lingo3g
