To help store and keep important but not often used commands I resorted to this. A basic for loop which when fed separate commands for its input searches the history and any references to that command or string gets appended to a file named [command name]_hist.txt
Revising it to the following though ti include root / sudo'd commands is probably critical the output above reflects the change, here below:
for i in docker elinks ufw fail2ban awk sed grep diff nginx apt bash for function bower github rsync sshfs who scp sftp tugboat aws pip npm ssh mysql php 8000 8080 3000 python serve s3ql s3cmd s3api s3 bash init wget; do cat /home/ray/.bash_history |grep -i "$i" >> /home/ray/histories/"${i}"_hist.txt;sudo cat /root/.bash_history |grep -i "$i" >> /home/ray/histories/"${i}"_sudo_hist.txt;done
then a simple more to look for a particular result
more -s -40 -p -f -d tugboat*txt
simple, solved my problem and alerted me to a lack of certain appearances of commands that signal a bit of an issue Not so sold on the usefulness as to warrant a bash function or further convenience or logic we shall see. Could use some tweaking but what commands dont!

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.
