This is a benchmark for fuzzy query.Every test will find the specific words within 10,000 lines.It will run serveral times to get the average result.

#Intro If you want to run the test in your environment. Two scripts in utils may help you. With init.sh, you can init your python lib、mysql db(mysql db will be initialized at data/mysql) With start.sh, you can run the test.

./utils/start.sh -h

This tool will make a benchmark about 'fuzzy query' in different way.
Every test will find the matched strings within 10,000 lines(data/list, this resource was created randomly, you can replace it)

usage ./utils/start.sh [options] [args] <TEST PROJECT1> <TEST PROJECT2> ...

<TEST PROJECT> php、hhvm、nodejs、python、java、webbrowser、mysql、sqlite

-w ARG     query word, default: abc
-t ARG     times in every test, default: 10
-d ARG     [on/off] need detail info in every test, default: off

Testname with word 'all' acts like %str%. Testname with word 'head' acts like str%.

In nodejs and chrome, the javascript engine is v8, v8 compile regex automatically, so there is no promotion after the compile. But in python, compiling regex can take a huge promotion.

In mysql, fuzzy query like str% can use index, but %str% can't.

What happened to php？

#My Test The following output was created in my env(queryWord：i5y times: 15).

php 5.4.33
php 7.0.12
hhvm HipHop VM 3.0.1
node 4.3.2
python 2.7.3
java 1.8.0_101
mysql 5.5.50
sqlite 3.11.1
