Some help please

Hello,

I have the ajax search lite plugin and i am really pleased with it.
There is only one thing i would love to change.
My whole site is written in dutch, and the option box of the search bar is in english.

I’ve been trying to change the text of this into dutchh. I changed the following code:

$options[‘asl_defaults’][‘exactmatchestext’] = “Exact matches only”;
$options[‘asl_defaults’][‘searchinpoststext’] = “Search in posts”;
$options[‘asl_defaults’][‘searchinpagestext’] = “Search in pages”;
$options[‘asl_defaults’][‘searchintitletext’] = “Search in title”;
$options[‘asl_defaults’][‘searchincontenttext’] = “Search in content”;
$options[‘asl_defaults’][‘searchincommentstext’] = “Search in comments”;
$options[‘asl_defaults’][‘searchinexcerpttext’] = “Search in excerpt”;
$options[‘asl_defaults’][‘searchinbpuserstext’] = “Search in users”;
$options[‘asl_defaults’][‘searchinbpgroupstext’] = “Search in groups”;
$options[‘asl_defaults’][‘searchinbpforumstext’] = “Search in forums”;

this code is located in: /ajax-search-lite/backend/settings/default_options.php

I also tried to change a few things in the /ajax-search-lite/backend/tabs/instance/general_options.php

But none of those seemed to work. I even deleted every thing in those files, uploaded to the site, and the search bar still worked…

Can somebody please help me with this?
The following link is an screenshot of a dummy site i created in which i could change it and that is how i want to have it.
