So now I hope you understand the running time of look
up well enough to be able to answer this question. This is
definitely a fairly subjective question. And the question is, is our
look up fast enough? So the possible answers are yes, that it
is fast enough, that it depends on how many key words
there are in the index, that it depends on how many url's
there are, meaning the number of different pages that we crawled in
our web crawl. That it depends on how many look-ups we expect
to need to do. Or no; that it's not fast enough.

あなたが把握しているとうれしいです
とても主観的な問題ですよ lookupは十分速いですか？
選択肢は“十分速い” “インデックスにあるキーワード数で速さが決まる”
“URL数つまりクロールした様々な ページ数によって決まる”
“行う必要があると予測したlookup数によって決まる”
“全然速くない”
