After adding the AJAX Search widget on the page, scroll down the AJAX Search Query settings.

To search in posts, pages, WooCommerce products, and CPTs created with JetEngine, do not turn on this toggle but specify the search scope in the Source field. The search area will cover the entire website content if this field is empty.

The Sentence Search toggle, if enabled, allows searching in sentences.

If enabled, the toggle Search in taxonomy terms specifies the search area as categories, tags, formats, etc. 

This setting is connected with the Content section of the Search Form block. Therefore to provide the proper search, enable the Show Categories List toggle from the Search Form block and specify the area for the search (as categories, tags, etc.) from the drop-down menu.

The last four settings cover the search result displaying:

• Results Order By makes it possible to choose from the drop-down menu the way to present result order: by Relevance, ID, Author, Title, Date, Last modified, Rand, Number of Comments, and Menu Order;

• Results Order sets the ASC (default) or DESC order;

• Posts Per Page has a field to type the number of results displayed on one search page;

• Posts Number has a field to type the number of results in one search query.

Turning on these settings proceeds with the necessary search results. 

Enter the page you want to add the search bar block and add the Ajax Search block to the place you want.

The Search Query is the second setting block of the AJAX Search block. It has two settings to specify the search areas: the Search by the custom query and the search in specific sources.

To search only in the current custom query, toggle the Search by the current query and type one or some custom fields in this field. This tutorial explains How to Set up a Field Key for Searching in Custom Fields for Gutenberg.

The search in specific sources covers the possibility to conduct searches in particular search areas such as posts, pages, landing pages, and custom posts developed with the JetEngine plugin. If this field is empty, the search will be conducted in all site data.

Besides, searching in complete sentences is possible by turning on the toggle Sentence Search.

If enabled, the next toggle Search in taxonomy terms makes it possible to include the search results in the posts with terms of the selected taxonomies.

The following four settings control the search result appearance. They are:

• Results Order to put results in the ASC or DESC order;
• Posts Per Page to specify the number of results displayed on the search page;
• Posts Number to type the number of results displayed in one search query.
