Answer 1

I'm using combobox with queryMode : 'remote' and doing a search withing combobox for matches. I'm doing a 'contains' search - meaning it looks for matches anywhere in the result string not just beginning and also it searches for values not only in current page but in the entire resultset. I'm using extjs 4.0.7 and i achived it by overriding doQuery method.
`doQuery: function(queryString, forceAll) {
this.expand();
this.store.clearFilter(!forceAll);
if(this.queryMode == 'remote') {
this.store.load({
params: this.getParams(queryString)
});
}
if (!forceAll) {
this.store.filter(this.displayField, new RegExp(Ext.String.escapeRegex(queryString), 'i'));
}
}`

your store needs to be setup for pagination
your server needs to handle pagination correctly based on the parameters received from the store's proxy. The proxy will send up querystring parameters like ?page=1&start=0&limit=25, and your server needs to return only 25 (for example) records and a total parameter.
{"total":101,"data":[{model data}, {model data}, ...]}
despite the documentation, the pageSize property in combobox is actually a boolean, turning pagination on if 1 or greater.
