QUESTION
When I check the firefox settings for searchengines I can see a column for keyword
In the opensearch.xml I can define Tags
which does not create an entry here. When I add my own opensearch, I want to also set the "Keyword". How do you do that?
My opensearch.xml
looks like this so far and is working (I can add the search in firefox over the green plus icon in the search bar):
ANSWER
Answered 2021-Jun-08 at 12:02As the keyword entry is a user-defined shortcut, you can't set it in your opensearch.xml.

hi i am having a problem where pressing enter appends values while the input field is focused. what i want to do is press enter and then it brings me to google bing etc. So before searching my url is http://127.0.0.1:5500/Newtab%20Home/index.html then pressing enter while searching "what is today" it changes the url to http://127.0.0.1:5500/Newtab%20Home/index.html?searchText=what+is+today&whichEngine=Google when i want it to search on google not 127.0.0.1

...ANSWER
Answered 2021-Mar-03 at 02:13Your problem was caused by your confusion, I believe, something very simple. In when you click on keyCode 13 (Enter), it calls the Submit event of the form, to resolve this you can get the and get the submit event using the preventDefault on it. Another problem was in the input you took, first that it is inside the startSearch function does not make much sense, then you were taking an id that does not exist, the correct id name was "sInput".

I am trying to understand whether a legacy app that generates a compass 2.2 index, stores the contents of fields or not, I can open the index with luke.net and from my understanding it's not storing fields, it just returns an id, presumably to be used elsewhere to select from a db
see this for lucene : Lucene Field.Store.YES versus Field.Store.NO
how can I tell whether this compass application indexes with the equivalent of lucene.net Field.Store.NO , this is the compass.cfg.xml :
...ANSWER
Answered 2021-Feb-10 at 19:51The easiest way to know which fields are stored for a lucene document is to open the index via lucene and to read in a document and then look at the list of fields for the document. Fields that are indexed but not stored will not show up in the list of the fields for the document.
Here is an example in Lucene.Net 4.8 that I wrote for you that hopefully can give you an good idea of how to check which fields are stored for a document. The syntax for you will of course be a bit different if you are using Java rather than C# and you will be using an older version of Lucene. But this chunk of code should hopefully get you a long way there.
In this example there are two documents added each with three fields. But only two of the three fields are stored, even though all three fields are indexed. I have placed a comment in the code where you can see which fields are stored for each document. In this example only two fields for each document will be in the d.Fields
list because only two fields are stored.

I am working on a search box where I used Flask, MySQL and Ajax to get the search suggestion while writing any query. I am getting response from the ajax call back when I start writing in the search box and I am appending new option which generate lot's of duplicates option because suggestion can be similar in another response so I want to delete that.
Here is the duplicate option problem
(In the Right Side You Can see the duplicates option showing in console) -
Here is my Ajax -
...ANSWER
Answered 2021-Feb-02 at 13:09I'd suggest you not just add new values, but form new list of options and replace old one with it. So, instead of $('#results').append(options)
you go with $('#results').empty().append(options)
. This way you will have only new options and no duplicates (unless there is some in your data).

I have created a new project and am trying to set up the production environment properly. I haven't added any entities yet so it's still an empty JHipster project! Unfortunately Elasticsearch keeps throwing an exception and it doesn't work out of the box.

...ANSWER
Answered 2021-Jan-12 at 11:25I found the error after all. It was really strange because sometimes everything started normally. After a closer look, the Elasticsearch Docker container did not always start. Error code 137! This of course made it impossible for my app to connect to ES. I have increased the resources of Docker (described here). Now everything is running fine!
