# Query String

It can sometimes be helpful to update the browser's query string when your component's state changes.

Let's say we are building a component to search articles.

```html
<!--- ./wires/SearchArticles.cfm --->
<cfscript>
    data = {
        "search": ""
    };
</cfscript>

<cfoutput>
    <div>
        <input wire:model="search" type="search" placeholder="Search articles...">
    </div>
</cfoutput>
```

We can automatically populate the search property above from the URL query string by adding a *queryString* array to our component.

```
queryString = [ "search" ];
```

```html
<!-- ./wires/SearchArticles.cfm -->
<cfscript>
    queryString = [ "search" ];

    data = {
        "search": ""
    };
</cfscript>

<cfoutput>
    <div>
        <input wire:model="search" type="search" placeholder="Search articles...">
    </div>
</cfoutput>
```

Now when we access the page with 'search' included in the query string (*/search-articles?search=some+string*), the search property will have a default value of "some string".

In addition to this, when the user starts typing into our search field, the URL displayed in the browser will be instantly updated.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cbwire.ortusbooks.com/3.x/wire-features/query-string.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
