One of the things that is slow is searching where all the search terms are single digit numbers. If you know you
are looking for a decimal number, it is worthwhile to add "keyword:cons" to the search. It helps either way, but
from my quick test, it works better if you put the "keyword:cons" first. That could just be random variation: I
didn't want to do extensive testing, for obvious reasons.

Here are my results:

3.1415926 - 9.832 seconds
3.1415926 keyword:cons - 6.840 seconds
keyword:cons 3.1415926 - 6.188 seconds

Subject: [seqfan] Don't submit a difficult query more than once, it kills the system

Dear Seq Fans,Some  queries take a while to be answered.
Queries with lots of 0's and 1's, for instance.
Or some queries that don't have commas, like this one:” 32 39 29 20 37 24 16 29 43 26” (without the quotes)
If you submit a query on the OEIS web page, and you don't get an answer right away, then *PLEASE WAIT*, 
and *don't submit it again**and again*. Each time it slows down the server, and this afternoon around
14:00 EST there were multiple submissions of one query that
essentially crashed the OEIS.
