I have to disagree. For starters the link that you gave with the terms that you used did not get the sequences that I stated. Also, you have to enter terms, I am sure you would not want to enter all of the terms for a sequence to test if it matches another one such as the ones that I stated. In other words, it does not work well the way it is now for a sequence search using the sequence name.

The keyword subseq: already exists and does something like what you want.
Try https://oeis.org/search?q=subseq%3A2%2C+3%2C+7%2C+23%2C+89%2C+113%2C+523%2C+887%2C+1129%2C+1327%2C+9551 Charles Greathouse
