What is the version of your community? It working fine on 17.10.
There is no separate filter for a tag on the search page. However, it still searches the messages with the tag name if you type the tag name inside the search box.
The main thread should contain that tag which you are searching for.
There is an API available for searching the messages using tag https://community.lithium.com/t5/Developer-Documentation/bd-p/dev-doc-portal?section=commv2&collecti...
Seems to be working fine here on the Lithium Community running 17.10, e.g. searching for the "tag issue" tag you used on this topic I get a highlighted match:
I'm not sure if you were referring to a specific search syntax that would only search in tags. Could be that the sad smiley in your original message ate half of it. Maybe you can clarify what search term you were using and if you would expected only tag matching then.
I confirm what your seeing but we have one stakeholder who used to use
As far as I was aware this wouldn't search only by tags but I wanted to be sure I wasn't missing something.
Thanks for sharing that example. I learned something new today as I didn't know that functionality existed. I actually assume (not having verified by looking at code though) that this must be some sort of special ElasticSearch syntax probably. It behaves a bit erratic though:
I'm wondering if this is a feature at all or if we are making a connection based on observing search results that might be just coincidence. The search results for "DAX" tags is pretty convincing, but e.g. on the bottom of page 30 of the search results I see a message that doesn't even have any tags: http://community.powerbi.com/t5/forums/searchpage/tab/message?q=tags%3A%28DAX%29&nospellcheck=true&p...
Just wandered around the (virtual) hallways of Lithium Community dev and picked up that what you are describing there is some part of the Lucene query language being exposed. This isn't anything we are actively testing and supporting though.
The query syntax to concatenate multiple tags would be
but the results seem to be a bit off, e.g. here's search results for "DAX and RLS" which I took from PowerBI community's tag cloud:
