In such cases, the Trac query engine is your friend:

A search for tickets with "searchforest" in the summary

https://trac.sagemath.org/query?order=id&desc=1&summary=~searchforest 

reveals ticket 16351.

You can also query for tickets with "searchforest" in the description:

https://trac.sagemath.org/query?order=id&desc=1&description=~searchforest 

and there are many other options, see:

https://trac.sagemath.org/query

This is so useful that I added a "search engine shortcut"
to my browser. Often browsers have shortcuts to search
on bing, duckduckgo, google, wikipedia, ...

b stuff
d stuff
g stuff
w stuff

so why not add tsum and tdesc ("trac summary", "trac description")
to be able to search using

tsum stuff
tdesc stuff

respectively defined as

https://trac.sagemath.org/query?order=id&desc=1&summary=~%s
https://trac.sagemath.org/query?order=id&desc=1&description=~%s

See this howto for how to set custom search engines
in various browsers:
