Use QueryBuilder objects to build queries used in webapi search

Query builder lets you convert a query object to magento2 required search query format which looks something like

searchCriteria[filter_groups][<index>][filters][<index>][field]=<field_name>
searchCriteria[filter_groups][<index>][filters][<index>][value]=<search_value>
searchCriteria[filter_groups][<index>][filters][<index>][condition_type]=<operator>

You can read more about using REST api on magento2 devdocs

Keep in mind following things mentioned on devdocs.

• To perform a logical OR, specify multiple filters within a filter_groups
• To perform a logical AND, specify multiple filter_groups
• You cannot perform a logical OR across different filter_groups, such as (A AND B) OR (X AND Y). ORs can be performed only within the context of a single filter_groups

const {QueryBuilder} = require('mage2-webapi');
//ES6 modules
import {QueryBuilder} from 'mage2-webapi';

How to use QueryBuilder Constructor

 let builder = new QueryBuilder();
    builder.addFilterGroup([
        {
            'field':'from',
            'value':'today',
            'condition':'eq'
        },
        {
            'field':'to',
            'value':'tomorrow',
            'condition':'eq'
        }
    ]);
    
     builder.addFilterGroup([
            {
                'field':'revenue',
                'value':'100',
                'condition':'lt'
            },
            {
                'field':'revenue',
                'value':'400',
                'condition':'gt'
            }
        ]);
    
console.log(builder.getQuery());
