[seqfan] Forcing of exact searches?

[Hugo Pfoertner]

SeqFans,

is there a method to force "exact" searches for words?
A search
https://oeis.org/search?q=%22factorization%22+keyword%3Ahard&sort=&language=&go=Search
produces 922 hits, because the occurrence of "factor" also produces a - in
my case unwanted - match.
I can not see that the search hints https://oeis.org/hints.html deal with
this problem.
