## Search through the UI

WebViewer, DOCX Editor, and Spreadsheet Editor each have a text search panel built into the UI to handle searching in their respective file types.

## Search programmatically

Searching for text can be performed using programmatic APIs:

{% tabs %}
{% tab title="JavaScript" %}
{% code lineNumbers="true" %}

```js
WebViewer(...)
.then(instance => {
  const documentViewer = instance.Core.documentViewer;
  
  documentViewer.addEventListener('documentLoaded', async () => {
    const searchStream = documentViewer.search('search_term'); // Setting up stream using your string to search.
    const searchResults = await searchStream.getAll(); // Wait for all results.
    console.log('search results:', searchResults);
  });
});
```

{% endcode %}
{% endtab %}
{% endtabs %}

For more precise results, you can add [Search.Mode](https://sdk.apryse.com/api/web/Core.Search.html#.Mode__anchor) options to better refine the results:

{% tabs %}
{% tab title="JavaScript" %}
{% code lineNumbers="true" %}

```js
WebViewer(...)
.then(instance => {
  const { documentViewer, Search } = instance.Core;
  
  documentViewer.addEventListener('documentLoaded', async () => {
    const searchMode = [Search.Mode['WHOLE_WORD'], Search.Mode['CASE_SENSITIVE']];
    const searchStream = documentViewer.search('search_term', searchMode); // Setting up stream using your string to search with whole word and case sensitivity.
    const searchResults = await searchStream.getAll(); // Wait for all results.
    console.log('search results:', searchResults);
  });
});
```

{% endcode %}
{% endtab %}
{% endtabs %}

[DocumentViewer.search](https://sdk.apryse.com/api/web/Core.DocumentViewer.html#search)

You can also progressively search for text if you don’t want to wait for the entire list of search items to be retrieved:

{% tabs %}
{% tab title="JavaScript" %}
{% code lineNumbers="true" %}

```js
WebViewer(...)
.then(instance => {
  const documentViewer = instance.Core.documentViewer;
  
  documentViewer.addEventListener('documentLoaded', async () => {
    const searchStream = documentViewer.search('search_term'); // Setting up stream using your string to search.
    const searchResults= [];
  
    for await (const result of searchStream) {
      searchResults.push (result); // Progressively adding results to an array.
      console.log('search result found:', result);
    }
  });
});
```

{% endcode %}
{% endtab %}
{% endtabs %}

## 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://docs.apryse.com/web/search/text-search.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.
