#### 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][][filters][][field]=
searchCriteria[filter_groups][][filters][][value]=
searchCriteria[filter_groups][][filters][][condition_type]=
`

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

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

How to use QueryBuilder Constructor

`javascript
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());

/** Console output
* 'searchCriteria[filter_groups][0][filters][0][field]=from&' +
'searchCriteria[filter_groups][0][filters][0][value]=today&' +
'searchCriteria[filter_groups][0][filters][0][condition_type]=eq&' +
'searchCriteria[filter_groups][0][filters][1][field]=to&' +
'searchCriteria[filter_groups][0][filters][1][value]=tomorrow&' +
'searchCriteria[filter_groups][0][filters][1][condition_type]=eq&' +
'searchCriteria[filter_groups][1][filters][0][field]=revenue&' +
'searchCriteria[filter_groups][1][filters][0][value]=100&s' +
'earchCriteria[filter_groups][1][filters][0][condition_type]=lt&' +
'searchCriteria[filter_groups][1][filters][1][field]=revenue&' +
'searchCriteria[filter_groups][1][filters][1][value]=400&' +
'searchCriteria[filter_groups][1][filters][1][condition_type]=gt';
