# Advance search:

This module help to build advance mongodb search queries.

Like........  

EX.  

(nodejs ANd php or angullar 4)  

(nodejs or (java and (angular 2 or (reactjs and javascript))))  

(nodejs and php or (java and php or (mongodb and typescript)))  

(sql and (mongodb or (dynamodb oR (redis or dynamodb) or (mongodb and javascript))))  

# How to use it:

const gk = require('and-or-search');

Example: (Support collection array & string attributes)

1. let res = gk.query('(nodejs AND (java or php))', 'skills', 'array');

2. let res = gk.query('(tom or jon)', 'first_name', 'string');

 -> 1st parameter is infix expression.  

 -> 2nd is the name of collection attribute.  

 -> 3rd is the type of collection attribute (array or string).  

Pass the response query to mongodb for search.  

let res = gk.query('(nodejs AND (java or php))', 'skills', 'array');  

 db.collection('user')  

   .find(res.query)  

   .then(result => {  

    //  

   }).catch(err => {  

    //  

   })  

 # Response types:

 { message: "success", code: 200, query: [object] }  

 { message: "Please provide expression to evaluate", code: 400, query: {} }

# User collection:

{  

    "_id" : ObjectId("5c30e7c172fbebb2a8776d2c"),
