In example of 1.1 and 2.0, under examples/form/custom.html
there is a nice searchable grid, it great a customized search box but when I try to test and use it, it has the following issue,
#1 initially it return all pages
#2 search (for example 'ajax') return limited pages,
#3 but when I using the pagingToolbar to page it, it return to the full search,

I study and got a little adjustment like this

From
PHP Code:
     onTrigger1Click : function(){
        if(
this.hasSearch){
            var 
= {start0};
            
o[this.paramName] = '';
            
this.store.reload({params:o});
            
this.el.dom.value '';
            
this.triggers[0].hide();
            
this.hasSearch false;
        }
    },

    
onTrigger2Click : function(){
        var 
this.getRawValue();
        if(
v.length 1){
            
this.onTrigger1Click();
            return;
        }
        var 
= {start0};
        
o[this.paramName] = v;
        
this.store.reload({params:o});
        
this.hasSearch true;
        
this.triggers[0].show();
    } 
To
PHP Code:
     onTrigger1Click : function(){
        if(
this.hasSearch){
            var 
= {start0};
            
o[this.paramName] = '';
            
this.store.baseParams[this.paramName] = '';
            
//this.store.reload({params:o});
            
this.store.reload();
            
this.el.dom.value '';
            
this.triggers[0].hide();
            
this.hasSearch false;
        }
    },

    
onTrigger2Click : function(){
        var 
this.getRawValue();
        if(
v.length 1){
            
this.onTrigger1Click();
            return;
        }
        var 
= {start0};
        
o[this.paramName] = v;
        
this.store.baseParams[this.paramName] = v;
        
this.store.reload();
        
this.hasSearch true;
        
this.triggers[0].show();
    } 
Maybe have better ways, but this workable, hope can be helpfully.
This can be apply to 2.0 dev version as well, thanks
