Hi Kyung, do you mean something like this

I used the SearchDataTableEntries Service to get the data with the exception that instead of SearchExpression parameter i am using the Query and this is what i pass to the SearchDataTableEntries : see below
var query = {
"filters": {
"fieldName": "stringCol1",
"type": "LIKE",
"value": searchString
}
};
var params = {
maxItems: 100 /* NUMBER */,
//searchExpression: /* STRING */
query: query /* QUERY */,
//source: undefined /* STRING */,
//tags: undefined /* TAGS */
};
// result: INFOTABLE dataShape: "undefined"
var result = me.SearchDataTableEntries(params);
I think the searchExpression will also work, it's just about figuring out the syntax for that as well.
In the meantime hope this helps
