Does multiple tag search support AND vs OR?

alehandrof · 19 يناير 2017، 8:02م

أعتقد أن هناك خطأ عند البحث عن علامات متعددة. إليك النتيجة الغريبة التي حصلت عليها على Discourse الخاص بي:

ig src=“//cdck-file-uploads-global.s3.dualstack.us-west-2.amazonaws.com/meta/original/3X/9/d/9d9e5d0ba84892a132ca1505ed87d1e7deb222b4.png” width=“690” height="428"

استنادًا إلى نتائج البحث، يجب أن يكون هناك 8 نتائج. لكن يعرض 9 نتائج. النتيجة الثانية صحيحة، لكن الأولى ليست كذلك.

أتساءل إذا كانت المشكلة تتعلق بالشرطة، حيث أن النتيجة الخاطئة تحتوي أيضًا على وسم -reports والذي يتضمن بعض مصطلحات البحث. المشكلة لا تظهر عند البحث عن committee-reports فقط.

I might be reading this wrong, but wouldn’t this simply imply the topic only needs to contain one of the provided tags?

github.com/discourse/discourse

lib/search.rb

0a78ae739


      
          advanced_filter(/tags?:([a-zA-Z0-9,\-_]+)/) do |posts, match|
            tags = match.split(",")
          
            posts.where("topics.id IN (
              SELECT DISTINCT(tt.topic_id)
              FROM topic_tags tt, tags
              WHERE tt.tag_id = tags.id
              AND tags.name in (?)
              )", tags)
          end

Or am I reading that incorrectly?

I guess it’s late

Thanks for pointing out what should have been obvious.

Is there a way to search for two tags with AND instead of OR?

بناءً على نقل هذا الموضوع إلى فئة #contribute:feature، أعتقد أن الإجابة هي لا – مؤقتًا

FWIW, I was just doing a multiple tag search to share a list of posts with someone and expected the search would return the intersection (AND) instead of the union (OR). So, found this post and adding a +1 for the option to AND multiple tags in a search.

@burke, you can actually do it but it isn’t performant (depending on the number of tags and topics you have)

You would specify the tag item multiple times, such as tag:pr-welcome tag:foobar

Hi,
Outreachy aspirant here I have successfully installed and run Discourse locally on my machine based on the instructions provided in the Beginners’ development guidelines. I am going through the codebase currently and was trying to get started on a beginner level issue. Is this a good place to start?
Thanks.

I am afraid this is a bit involved, I would pick something a bit more straight forward. PM me with a list of 5 or so features/bugs you find interesting and I will help guide you to the best place to start.

alehandrof · 20 فبراير 2017، 8:51ص

Thanks for pointing out to this helpful workaround @cpradio!

medha · 22 فبراير 2017، 2:44ص

Thanks for the guidance, I am now looking for issues that I am able to understand/find interesting.
Also, there is a lock icon many of the issues. Does that imply they are not open to all contributors?

Closed topics are topics we are done with, they are completed.

With this pull request now it is possible to do logical AND search by multiple tags and the performance is the same for any number of tags. Example search: tag:pr-welcome+foobar
