esquery | Elasticsearch | SQL Database library

I have installed new Windows OS in PC recently and lost all my settings. I have installed node in my system and two global npm packages. But when i am running this command npm list -g --depth=0 or npm list -g then money errors are here. I have tried to install eslint but nothing resolved.

The error list is here,

I'm using an older version of node (6.17.1) and had explicitly installed eslint@5.16.0 as the newer versions of eslint don't work with node 6. This had been working without any problems for a while.

Recently, when installing eslint@5.16.0 from package.json using npm install no longer works -- there is now an incompatible dependency that I assume is somewhere in eslint's dependency tree.

My question is, was npm install on a specific version of eslint expected to continue working forever in the same way? Or is this normal for npm packages (of a specific version) to have some package deep in the dependency tree change, and then break that specific version of the first package?

And if this cannot be prevented, is there any way to easily fix this once a dependency breaks? Is this what package-lock.json is for?

The error output from npm is below:

I am using ElasticSearch 7.3, to query some documents,
I want to return only specific fields of each document in the query response,
I found that _source can be used to achieve this,
Which I was able to do from Kibana using this query -

I upgraded from:

• ElasticSearch 2.0 to 6.6.1
• ElasticSearch.Net Nuget package 2.4.6 to 6.5.1
• NEST NuGet package 2.4.6 to 6.5.1

...and my Nest query to do a MatchPhrasePrefix stopped returning results.

The software is a search engine for web pages, and one of the features is supposed to let you limit the results to URLs that start with a certain path, like http://example.com/blog to see only blog posts in the search results.

I have a mainQuery that works fine. If the user supplies a urlStartstWith value the mainQuery gets anded together with a bool / MatchPhrasePrefix query.

The indexes contain anywhere from 100s to 1000s of documents.

Things I have tried that did not work:

• Completely rebuilt the new index
• Removed the .Operator(Operator.And) since it does not exist in this version of NEST (caused compile error)
• Upping "MaxExpansions" to various values all the up to 5000
• URL-Encoding urlStartstWith
• Removing the .MinimumShouldMatch(1) line

If I run this query built with the new NEST library against the old ElasticSearch version 2.0 server, it works. So it's something that has changed under the hood in ElasticSearch itself I think.

The Query

I must be doing something fundamentally wrong here. I'm trying to get a "More Like This" query working in a search engine project we have that uses Elastic Search. The idea is that the CMS can write tags (like categories) to the page in a Meta tag or something, and we would read those into Elastic and use them to drive a "more like this" search based upon an input document id.

So if the input document has tags of catfish, chicken, goat I would expect Elastic Search to find other documents that share those tags and not return ones for racecar and airplane.

I've built a proof of concept console app by:

• Getting a local Elastic Search 6.6.1 instance running in Docker by following the instructions on https://www.elastic.co/guide/en/elasticsearch/reference/current/docker.html

• Creating a new .NET Framework 4.6.1 Console App

• Adding the NuGet packages for NEST 6.5.0 and ElasticSearch.Net 6.5.0

Then I created a new elastic index that contains objects (Type "MyThing") that have a "Tags" property. This tag is a random comma-delimited set of words from a set of possible values. I've inserted anywhere from 100 to 5000 items in the index in testing. I've tried more and fewer possible words in the set.

No matter what I try the MoreLikeThis query never returns anything, and I don't understand why.

Query that isn't returning results:

I have to upgrade one of my customer's web site from Symfony 2.8/Elastic Search 1.7/FOS\elastica-bundle" 3.2 to 3.4/6.2/5.0.3.

I have made a copy of the existing web site on a brand new server with Elastic Search 6.2 installed.

I have read many about this and understood I have to rewrite the Bundle that managed Elastic queries because a lot of methods are outdated, specially DSL filters.

Di you have any idea of what the following code (in the Bundle controller) would become in ES 6.2 :

I'm running bosun to alert against an elasticsearch data set.

The scenario is that there's a number of cron jobs that do various things. If these execute successfully, they will log a success message. If they die / fail to run for whatever reason and fail to log the success message, we need to know about it.

My question is how to get a 0 result if no record is found, rather than null. Here's the basic query:

I'm trying to filter my results by wildcard character.
