I have set up solr and it works. I have tested it by indexing my MySQL db and running queries on it, trying facets and trying the term suggest component (which I wish to use with autocomplete).
I have recently walked through the reuters tutorial here and it worked on my local machine.
Now my solr instance is on: "http://[someurl]::8983/solr/" and the instance they are using in the 'reuters.js' file is 'http://example.solrstuff.org/solrjs/'. How do I change the code to point to my instance - when I just swap the urls the code in the example doesnt work anymore - no search results are displayed. Do I need to install SolrJS or something? What is going on here?
Any help appreciated!
Do you have a typo in your URL? It looks like there are two colons in between the domain and the port number. http://[someurl]::8983/solr/ should be http://[someurl]:8983/solr/. You can test by entering that URL into a browser on your test machine. You should be able to get to the Solr admin page from there and do a query. If you can't, it's a problem with your URL.

I created my very first NODEJS API. Locally, it works well but I just hosted it on planetHoster and it doesn’t work anymore. When I enter my query, I find the error "Cannot GET/Nodev2/idcc/list" then my route was functional locally. Do you have any assumptions? Thank you in advance!
I can share my code if you want see

We work on a product that is a series of components that could be installed on different CMSs and provide different services. We take a CMS agnostic approach and try to use the same code in all the CMSs as much as possible (we try to avoid using CMS API as much as we can).
Some part of the code needs to work with the current URL for some redirections so we use Request.Url.ToString() that is something that has worked fine in other environments but in Kentico instead of returning the current page we always get a reference to CMSPages/PortalTemplate.aspx with a querystring parameter aliasPath that holds the real URL. In addition to that, requesting the Template page using a browser gives you a 404 error.
Example:
Real URL (this works fine on a browser):
(1) https://www.customer.com/Membership/Questionnaire?Id=7207f9f9-7354-df11-88d9-005056837252
Request.Url.ToString() (this gives you a 404 error on a browser):
(2) https://www.customer.com/CMSPages/PortalTemplate.aspx?Id=7207f9f9-7354-df11-88d9-005056837252&aliaspath=/Membership/Questionnaire
I've noticed that the 404 error is thrown explicitly by the template code when invoked directly. Please see below code from Page_Init method of PortalTemplate.aspx.cs:
var resolvedTemplatePage = URLHelper.ResolveUrl(URLHelper.PortalTemplatePage);
if (RequestContext.RawURL.StartsWithCSafe(resolvedTemplatePage, true))
{
// Deny direct access to this page
RequestHelper.Respond404();
}
base.OnInit(e);
So, if I comment the above code out my redirection works fine ((2) resolves to (1)). I know it is not an elegant solution but since I cannot / don't want to use Kentico API is the only workaround I could find.
Note that I know that using Kentico API will solve the issue since I'm sure I will find an API method that will return the actual page. I'm trying to avoid that as much as possible.
Questions: Am I breaking something? Is there a better way of achieving what I trying to accomplish? Can you think on any good reason I shouldn't do what I'm doing (security, usability, etc)?
This is kind of a very broad question so I was not able to find any useful information on Kentico docs.
I'm testing all this on Kentico v8.2.50 which is the version one of my customers currently have.
Thanks in advance.
It's not really recommended to edit the source files of Kentico, as you may start to run into issues with future upgrades and also start to see some unexpected behaviour.
If you want to get the original URL sent to the server before Kentico's routing has done its work, you can use Page.Request.RawUrl. Using your above example, RawUrl would return a value of /Membership/Questionnaire?Id=7207f9f9-7354-df11-88d9-005056837252, whereas Url will return a Uri with a value of https://www.customer.com/CMSPages/PortalTemplate.aspx?Id=7207f9f9-7354-df11-88d9-005056837252&aliaspath=/Membership/Questionnaire (as you stated).
This should avoid needing to use the Kentico API and also avoid having to change a file that pretty much every request goes through when using the portal engine.
If you need to get the full URL to redirect to, you can use something like this:
var redirectUrl = Request.Url.GetLeftPart(UriPartial.Authority) + Request.RawUrl;
I'm starting playing with NodeJS and Socket.IO and I've got a question regarding communication between pages of my application.
I've got a Node JS script (get_new_data) which is periodicaly executed using a cron task. This script will get information through Internet, parse them and write them in a PG Database. This is ok.
I've got a secondary script (show_last_data) using Node/Express/Socket.io that displays the last information of the DB when it is executed. This is also ok, right now.
What I would like now, is that the script show_last_data would be notified when new data are inserted in the database and the corresponding display divs to be updated.
Can get_new_data connect to show_last_data even if it is not the server that produces the page ? Or should I manage this in another way ?
Thanks for help
I've finally found a way to manage this using socket.io-client.
This page was particulary helpful to solve my question : socket.io as a client
I have encountered a strange behaviour with express routes. I want to enter an ID via HTML-Form and fetch the result via ajav (jquery) to display the entry. All was working fine, till i have to expand the ID from numbers to strings (with slashes).
I edited all functions and calls. I check the strign with a reg ex and want to fetch the request with a modified route (express). but here comes the problem. i get it working under windows but it is failing on linux. Perhaps the problem is caused by the invrastructure, because the node.js app is located behind an reverse proxy apache2 to tunnel the service to public (with domain & cert).
what ever. perhaps somebody can help me set this thing up and get it running.
app.get(/^\/byId\/(.+)/, getSourceById);
not using req.params[0] in the called function. on the test server (windows) it is working even with the old route
app.get('/byId/:id', getSourceById);
because the html form does request %2F not /. How ever, both ways should work to fetch the request. But both aren't working for me. did i miss something?
i'm thankful for any help!
Found the answer of my question. It was indeed the reverse proxy who was blocking the request.

I am fairly new to both mongodb and node.js but recently got everything to work well for me until I reached the point where I needed to add a full text search to my website. From my research I figured out that Elasticsearch would be a good fit, but I couldnt figure out exactly how to get it to work with node.js and mongodb. I am currently using Heroku and MongoLab to host my application. Here are my questions.
How do I host Elasticsearch?
How do I make all my mongo data available to elasticsearch do I use a river or do I manually inset and delete all data?
I found something this river but I am not quite sure how to make this happen automatically and where to host it.
How do I query Elasticsearch from node.js? Is there a package that allows for this?
Edit:
Question 2 is really what I am struggling with. I have also included question 1 and 3 to help people that are new to the topic and coming from google.
1) either on your own server/VM/whatever.. or with a hosted service such as https://searchbox.io/
2) you can create a script to index your existing data and then index new data once its created, or use a river to index your current database.
3) ElasticSearch is a simple HTTP API, you can make your own requests using the 'http' module or simplify it with something like https://github.com/mikeal/request
you can also use a 3rd party library like https://github.com/phillro/node-elasticsearch-client
Searchly.com (Aka SearchBox.io)introduced a new feature crawlers includes MongoDB crawler.
It fetches data from a given collection and syncs periodically to ElasticSearch. Check http://www.searchly.com/documentation/crawler-beta/
You can host on your own server or use aws elasticsearch service or use elastic cloud provided by elasticsearch.
Try any of the following three solutions:-
i) Try using mongoosastic. NPM package
ii) Use mongo-connector.
iii) python script for indexing data to elasticsearch
elasticsearch-js. The javascript client library
