I recently upgraded Elastic Search from v 1.7 to 2.4. I'm working in python and using pyes library to communicate to Elastic Search. In my code, I have this line in place to refresh index.
con.indices.refresh()
This was working fine with ES 1.7, however with ES 2.4, I'm getting this exception:
ElasticSearchException: Unknown exception type: 408
Refreshing via curl works just fine, i.e
curl localhost:9200/_refresh
Is there any changes in Elastic Search 2.4 that is breaking this piece of code? Thanks
Did you update the version of pyes library. There is a version compatibility between ES and pyes. Which is strict.
refer to the documentation here.

I'm trying to integrate elsaicsearch with suitecrm.
I've followed the document as per https://docs.suitecrm.com/admin/administration-panel/search/elasticsearch/
Then I tried to run full indexing from suitecrm, I got "index_not_found_exception" hence created indexes manually in the elasticsearch.
After that also when I am trying to run the indexing, no logs showing in suitecrm or elasticsearch and search in elasticsearch is not working.
Suitecrm version
Version 7.12.5
Sugar Version 6.5.25 (Build 344)
Elasticsearch version
"number" : "7.17.5",
Please advise. Thanks.
I didn't get any suspicious logs in suitecrm.log so had enabled debug mode for the logs
https://docs.suitecrm.com/developer/logging/
Then I clicked on full indexing I found below log line
Elasticsearch trying to re-indexing a bean but this module is blacklisted: SchedulersJobs
I followed this document then https://docs.suitecrm.com/blog/scheduler-jobs/
And lastly this step Admin / Repairs / Quick Repair and Rebuild
After that it started working
I want to add stopwords to my project but I think Elasticsearch is not installed on my server. Search Engine as MYSQL is selected.
will our stopwords work or not without Elasticsearch configured?
Also, I want to make sure that elastic search is configured or not. For that I am using the command
curl -XGET 'http://localhost:9200'
and in response, I am getting output as:
curl: (7) Failed to connect to localhost:9200; Connection refused.
Does this signify that elastic search is not configured?
I got the proper solution to this question.
a) Install Elasticsearch6.0
b) Then follow the steps https://devdocs.magento.com/guides/v2.4/config-guide/elasticsearch/es-config-stopwords.html#to-change-directory-stopwords
But one thing that needs to be kept in the mind is:
Don't override the stopwords.csv file
Instead, override the stopwords_en_US.csv file i.e. according to your locale.
Your module will work perfectly.
The solution on all sites is perfect. Just we need to override the correct file for stopwords according to locale.
I have 2 questions:
Can I run spring-data-elastic v4.0.1.RELEASE (with org.elasticsearch:elasticsearch 7.6.2 ) with ES client running on 7.4.0??? If not, what combination can I use for 7.4.0 client? We are migrating to AWS and I need to use 7.4.0 version of client.
I have parent/child relationship (configured as join datatype field). Could pls somebody provide a documentation or explain, how to use either ElasticsearchRestTemplate or ElasticsearchOperations to correctly insert/update both parent and child records?
Thank you.
Best regards,
Robert
ad 1): from the Elasticsearch documentation I can't at the moment find anything in the breaking changes sections that would prevent using a 7.4.0 client library, but that does not mean there aren't any. But that does not mean that there aren't any. Recently there was a breaking change in the Java classes (from 7.7 to 7.8) and I got the information:
our compatability focus is on the HTTP APIs and we don’t offer any guarantees on the code itself. There’s more background here: https://github.com/elastic/elasticsearch/issues/22707#issuecomment-274163711
So I'd say, write a small test app and with the corresponding libraries, start a local ES 7.4 and test it.
ad 2): adding the join-type mapping ang implementing the corresponding inserts etc. is currently worked on and will hopefully be available in version 4.1.
Am trying to use elasticsearch with my neo4j database for fast querying.I tried many sites but they are all old articles so i didn't get any clear idea. Steps I followed until now,
Installed neo4j
Installed elasticsearch
Copy pasted elastic search plugins into neo4j plugins folder
added this line into neo4j. properties file
elasticsearch.host_name=http://localhost:9200
elasticsearch.index_spec=people:Person(first_name,last_name), places:Place(name)
Here my question is,
How elasticsearch and neo4j are integrated. Please clarify me on this.
I followed this ,
Link
You have to install Apoc procedures plugin (https://github.com/neo4j-contrib/neo4j-apoc-procedures). The documentation about ES integration is here : ES Integration with Apoc procedures
[edit]
download and drop apoc.jar in plugins's Neo4j directory, regarding the targetted Neo4j version
restart Neo4j
in Neo4j Web browser, launch the following Cypher query to show all ES procedures:
CALL apoc.help("apoc.es")
Sample query for logs:
CALL apoc.es.getRaw("localhost","_search?q=level:ERROR",null)
YIELD value
UNWIND value.hits.hits as hits
RETURN hits LIMIT 100
The recommanded way is to store the ES host in neo4j.conf by adding a key (after restart of Neo4j):
apoc.es.myKey.url=localhost
Then the query looks like:
CALL apoc.es.getRaw("myKey","_search?q=level:ERROR",null)
YIELD value
UNWIND value.hits.hits as hits
RETURN hits LIMIT 100
For those of you who already have APOC plugin installed and accessible, but don't have access to the neo4j.properties file (or are more comfortable working with ES through curl) you can do this without using apoc.es.getRaw and can instead use the JSON returned with apoc.load.json:
WITH "http://myelasticurl:9200/my_index/_search?q=level:ERROR" as search_url
CALL apoc.load.json(search_url) YIELD value
UNWIND value.hits.hits as hit
WITH hit._source as source

So I've been working on implementing elastic search using the JDBC River plugin to get data from our SQL Server DB into elastic search.
I've got it working fine using the SQL Server credentials, but trying to use integrated security doesn't work. It will create the index, but it doesn't have data in it.
The parameters I've been using are:
PUT /_river/test_river/_meta
{
"type":"jdbc",
"jdbc":
{
"driver":"com.microsoft.sqlserver.jdbc.SQLServerDriver",
"url":"jdbc:sqlserver://testServer:1433;databaseName=TestDb;
integratedSecurity=true;",
"user":"",
"password":"",
"sql": "select * from users",
"poll":"30s",
"index":"testindex",
"type":"testusers"
}
}
I've tried quite a few things, including removing the user and password fields completely, removing integratedSecurity=true, but it gave the same result.
I've checked on their github for the river plugin and it says this issue was fixed back in January, but it still doesn't seem to be working.
Also I'm using elastic search version: 1.5.1
and jdbc river plugin version : 1.4.0.10
Any help would be much appreciated
Get rid of the user and password options. You're not gonna need them.
Check the console when running elasticserch.bat, you should see an error message when it tries to update the river. I'm going to go out on a limb and assume you're probably seeing an error stating that the file sqljdbc_auth.dll can't be found. If this is the case, you can download this file from here and copy the x64 version of sqljdbc_auth.dll to your java lib folder. For me, this folder is C:\ProgramData\Oracle\Java\javapath but you can type echo %path% in a console window to find yours.
Once you have followed these steps, restart elasticsearch.bat, and it should start processing your river. If not, post back with the output you're seeing when running elasticsearch.bat.
