So, no help for me i guess

. Anyway, i tried some different character sets, but it doesn't work, and when I change the resource(document) name to latin it works better, but it only search in resource name, not the content. Maybe I am doing something wrong, so here is what I did from the beginning. I installed modx evo, made some templates and just paste the whole code from my web page into a template and created new page in modx and used the template i created. I copied my css and images into assets folder, and anyway the web page displays fine. I did this for 3 or 4 pages, so I created the template for every page. Here is the code for ajaxSearch:
<!-- start AjaxSearch header -->
<script type="text/javascript">
//<![CDATA] asvar=new Array();asvar[0]='{"vsn":"1.9.2","adv":"oneword","sub":"","bxt":"Упишите реч...","cfg":"&extract=`0` &ajaxMax=`10` &moreResultsPage=`6` "}';//]]>
</script>
<!-- end AjaxSearch header -->
Here is the code for search form:
<div id="search">
<form id="ajaxSearch_form" action="index.php?id=1" method="post">
<fieldset>
<input type="hidden" name="advsearch" value="oneword" />
<label>
<input id="ajaxSearch_input" class="cleardefault" type="text" name="search" value="Упишите реч..." onfocus="this.value=(this.value=='Упишите реч...')? '' : this.value ;" />
</label>
<label>
<input id="ajaxSearch_submit" type="submit" name="sub" value="Тражи" />
</label>
</fieldset>
</form>
<p class="ajaxSearch_intro" id="ajaxSearch_intro"></p>
<div id="ajaxSearch_output" class="init"></div></div>
So, is it possible to make ajaxSearch work with cyrilic characters. I can also copy here code from web page if that helps. Anyway, any help would be great, just to start from somewhere. Thanks.
