Experiment building the full list in redis

Preliminary result, after collating each sentence, 70972 items added to the sorted set.

127.0.0.1:6379> zcount icd9 -inf +inf
(integer) 70972

An example:
"1 - some test word"

will be collated as:

word
test word
some test word
1 some test work

the idea is when the user starts typing the query, anything come after it will be matched.
