AutoComplete and Minimum Length

QuestionsAutoComplete and Minimum Length
DGea asked 4 years ago

Hello,

I just make sure that the best way to reduce the load of data when using AutoComplete is to turn MINLENGTH.
So, not only do a search based on the begin of the word, but also can do a search in the middle of a word

However, I've tried to do it (Edit lib/inc/jqgrid_dist.php, Change: "minLength":1, to: "minLength":3,) but do not function properly.

My Question:
1. Is the new version is not there a problem about MinLength?
2. Is the new version supports the latest JQuery?

Hi,

1) MinLength should not ease the load of query. Mysql does not perform well with contains search. It only use indexes with begins with search. (like 'abc%'). I'm afraid this issue will exist as it is database performance isssue.

2) It uses jQuery v1.11.0
