# Introduction
The `WixSearchBuilder` functions enable you to run, filter, sort, apply facets (categorize), and control
 which results a search returns.

 Typically, you build a search using the [`search()`](wix-search.html#search) function,
 refine the search by chaining `WixSearchBuilder` functions, and then execute the
 search by chaining a [`find()`](#find) function.

 For example, the following searches a site for all store products containing the phrase
 "shoe" in English that are on sale, sorts them alphabetically according to their SKU, 
 and logs the first 5 results to the console:

 ```javascript
 import wixSearch from 'wix-search';

 wixSearch.search("shoe")
   .language("en")
   .documentType("Stores/Products")
   .eq("onSale", true)
   .ascending("sku")
   .limit(5)
   .find()
   .then( (results) => {
     console.log(results.documents);
   } );
 ```

Only some fields can be searched, filtered, sorted, or faceted. Check the supported schemas for each [`documentType`](#documentType):


 - [Blog/Posts schema](https://support.wix.com/en/article/velo-wix-blog-schema-for-wix-search)
 - [Bookings/Services schema](https://support.wix.com/en/article/velo-wix-bookings-schema-for-wix-search) 
 - [Forum/Content schema](https://support.wix.com/en/article/velo-wix-forum-schema-for-wix-search)
 - [Stores/Products schema](https://support.wix.com/en/article/velo-wix-stores-schema-for-wix-search)


To use the [`and()`](#and), [`or()`](#or), and [`not()`](#not) filtering functions, you first need to create 
`WixSearchFilters` using the [`filter()`](wix-search.html#filter) function
and the [`WixSearchFilterBuilder`](wix-search.WixSearchFilterBuilder.html) filtering functions. You can then 
pass the `WixSearchFilters` to the `and()`, `or()`, and `not()` functions.

Note that when you chain multiple filtering functions to a `WixSearchBuilder`, an `and` condition is assumed.
