Please tell me the way to serach some columns using by double-byte "space"

first of all, thank you for making this cool system !!

I found "datatables" is useful and speedy better than MySQL!





the other day, I downloaded "DataTables-1.9.4" and mada this site ↓







I could use "sort" and search box.

But, if I try to serach some columns using by more than two japanese words,

I can't find the column that is expected to be shown...


next, I changed "space"(double-byte character) into half-width characters.

So I could use more than two japanese words in search box.


For example,

"土居　酒田" is failure

"土居 酒田" is OK !

(how to read 土居＝doi　酒田＝sakata)





but this way is time‐consuming.
