Yes, apparently there is this feature… but I never see it being used?
I was browsing a little into the forum and bumped into the synonyms feature. It seems underused and should be very beneficial if we used this, because some tags are very similar to each other and should have those synonyms used which we can then use to find more topics with the selection of tags. Some people might not have all the words in their vocabulary and that might resolve some searching using tags.
Some tags that are approximately the same are: #composing and #composer.
