FAQ

Q: What is "In-page-Ajax-render" ?

A:

General GET/POST search flow is:

1. You input search term and click search button
2. Your browser loads the search term into a GET/POST query then sends it to target URL you specify
3. Your browser opens a new tab and loads the HTML responded by the target website

Big Search's In-page-Ajax-render search is:

1. You input search term and click search button
2. Your browser opens target website page you specified (search term not sent)
3. Big Search injects a simple JS to the page, filling your search term into the text box on page (according to css selector you specified). Then JS triggers clicking the submit button (also according to css selector you specified) action
4. The website page itself then uses Ajax to fetch search results, then your browser renders them on page

The In-page-Ajax-render search feature can be used to search websites that do not provide GET/POST search interface to public (e.g. SPA websites), or those who require random token assigned at a search entrance form.

"In-page-Ajax-render" is short for "In-page-submit-form-via-Ajax-then-XHR-gets-search-result-then-render-and-show-in-page-without-web-frame-navigation"

How to edit search engines (GUI or JSON)

Online GUI engine-editing tool (link 1) (link 2)

Generally, use above GUI editor. If you don't want to use GUI (e.g. you are advanced user and want to use advanced features), please go on and read below.

Big Search users can edit search engines programatically. Following paragraphs of this section are about JSON-format engine data specification. For both:

1. User-defined private engines
2. Big Search built-in search engines (enginesdata.js)

Examples

Short Format

You only need to write very simple JSON and have basic HTTP knowledge on GET Method.

{
    "Google": "https://www.google.com/search?q={0}",
    "Yahoo Search": "https://search.yahoo.com/search?q={0}"
}

Full Format

Using full format you have opportunity to use all the features of this tool.

Also, mixing short formatted and full formatted elements is supported.

Instructions for searching In-page-Ajax-render websites

Some websites doesn't provide GET/POST search (or not respond results in HTML). Visitor need to open their page then input, they then show results via Ajax on their page. (see FAQ)

Big Search can deal with such In-page-Ajax-render websites (by injecting js to your browser web, to automate inputting, clicking, form submitting). And easy to configure:

Eg 1: Specify the css selector of input box. It will automatically input search term and trigger pressing Enter event.

"ajax": "#search-box-input"

Eg 2: Delay 2s -> Input -> Delay 1s -> Trigger clicking button event

"ajax": [2000, "#search-box-input", 1000, "#submit-button"]

This part is also explained in the video description

For Developers

We encourage user to submit their customized search engines data to source code after they format as JSON (submit to file enginesdata.js)

What's Next Step

This tool still can be improved to do something more:

• Omnibox
• Be compatible with others e.g. OpenSearch. Add or convert by 1-click
