Is there a way to search the topic titles by keyword?

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: 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.
