ComboBox autocomplete: excluding some characters from triggering remote search

[Timido]

Hello!

I have a combobox with autocomplete function turned on to query against a remote URL.

It works just fine, and I use it to let the user select from a list of TAGS (yes, like those used in blogs).

I would like to have some characters excluded from triggering a remote search.

For example, if I type "av", the remote search should be triggered.
Then say I select the word "aviation" from the list.
Then if I type a single comma "," after aviation because I want to enter a new word, the remote search should not be triggered.

That is, typing just a single comma or a single whitespace should not trigger any search.
Still I want to trigger the search when I type even one single alphabetic character.

Is that possible?

This is my code:

var search = new Ext.form.ComboBox({
                store: store,
                displayField:'name',
                typeAhead: false,
                minChars: 1,
                loadingText: 'Searching...',
                width: 570,
                pageSize:0,
                hideTrigger:true,
                tpl: resultTpl,
                applyTo: 'search',
                itemSelector: 'div.search-item'
            });

I tried with maskRe but looks like it's the wrong way.
Thank you!

Guess I found the way

Anyway, any better idea is welcome of course

listeners: {

      'beforequery': function (queryEvent) {

             value = queryEvent.combo.getValue();
             re = /.*[,\s]+$/;
    
             if (value.match(re)) {
                 return false;
             }
             else {
                 return true;
             }

       }
}
