#Laravel Google Custom Search Engine
Laravel package to get Google Custom Search results from Google Custom Search Engine API for both free and paid version.
#### Brief history
As Swiftype closed free plans, I started to find some alternative without too much coding, but was unsucessfull.
The best I found was [Spatie's Google Search package](https://github.com/spatie/googlesearch) for Google CSE paid version, so I made
some research and develop package similar way, but independent to Google CSE version.
#### Coffee for developers
If you like this project, you can buy me a coffee to help me get fresh. :)

### Save the configuration values

## Usage
### Simple usage
Create an object and call the function getResults to get first 10 results
```php
$fulltext = new LaravelGoogleCustomSearchEngine(); // initialize
$results = $fulltext->getResults('some phrase'); // get first 10 results for query 'some phrase'
```
#### Do not forget to map namespace with, so sample controller will look like this (in min. way)
It is only example controller name, you can use whatever you want, this is notice mainly for novices in Laravel
```php
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use JanDrda\LaravelGoogleCustomSearchEngine\LaravelGoogleCustomSearchEngine;
class GoogleSearchController extends Controller
{
public function index(){
$fulltext = new LaravelGoogleCustomSearchEngine(); // initialize
$results = $fulltext->getResults('some phrase'); // get first 10 results for query 'some phrase'
}
}
```
You can also get information about the search like total records and search time
```php
$fulltext = new LaravelGoogleCustomSearchEngine(); // initialize
$results = $fulltext->getResults('some phrase'); // get first 10 results for query 'some phrase'
$info = $fulltext->getSearchInformation(); // get search information
```
### Advanced usage
You can use any parameter supported at Google. List of parameters is here:
https://developers.google.com/custom-search/json-api/v1/reference/cse/list#parameters
E.g. you want to get next 10 results
```php
$parameters = array(
'start' => 10 // start from the 10th results,
'num' => 10 // number of results to get, 10 is maximum and also default value
)
$fulltext = new LaravelGoogleCustomSearchEngine(); // initialize
$results = $fulltext->getResults('some phrase', $parameters); // get second 10 results for query 'some phrase'
```
You can also get the raw result from Google including other information
Full list of response variables is available here:
https://developers.google.com/custom-search/json-api/v1/reference/cse/list#response
```php
$fulltext = new LaravelGoogleCustomSearchEngine(); // initialize
$results = $fulltext->getResults('some phrase'); // get first 10 results for query 'some phrase'
$rawResults = $fulltext->getRawResults(); // get complete response from Google
```
For getting the number of results only use
```php
$fulltext = new LaravelGoogleCustomSearchEngine(); // initialize
$results = $fulltext->getResults('some phrase'); // get first 10 results for query 'some phrase'
$noOfResults = $fulltext->getTotalNumberOfResults(); // get total number of results (it can be less than 10)
```
If you have more engines / more api keys, you can override the config variables with following functions
```php
$fulltext = new LaravelGoogleCustomSearchEngine(); // initialize
$fulltext->setEngineId('someEngineId'); // sets the engine ID
$fulltext->setApiKey('someApiId'); // sets the API key
$results = $fulltext->getResults('some phrase'); // get first 10 results for query 'some phrase'
```
