For example, I tried searching for read or blue circles on map. With 134 pages of topics, that search is difficult and time consuming.
Google: site:forum.openstreetmap.org josm red and green circles
although you may not find anything useful. (I have never noticed any).
Thank you for responding. I already had tried that.
The topic of this question was “How to search forum titles by keyword.” I had submitted separately the colored circles question to Google already.
