There should be a lot of people encountered

joomla search, it will limit your website requires a minimum input search characters
Default is 3 words
There have trouble ...
Because sometimes I want to search the characters are [旅遊(travel)]. When [電玩(video)] this word only two characters in UTF-8
Can not be searched

So I wrote a special plug-in to solve this problem today
But also the way to develop joomla3 plug with you explain the basic file

 

Basically only zoearth_search_word_limit.php and zoearth_search_word_limit.xml file is the key
in  http://docs.joomla.org/J3.x:Creating_a_search_plugin  have more info

In fact, not much use archives
Languages files can even do not need to
Emphasis is

Profile at the beginning of  type="plugin" group="search"
and in xml
zoearth_search_word_limit.php

Because these two setpoints will decide this plug-in start-up mode and location
It is not possible to set an error

I hope that plugin helpful
if have questions you can ask me!
Thanksgiving !!
Together use joomla3!
