Ebay webservices request developers to cache results, in order to limit amounts of calls to servers and to receive ebay approval as a certified application. (raise api limits from 5k to 1.5mk).

One possibility Im thinking about is to create a store key-value to retrieve a particular search. if a file is created which key can be trigger to detect the same kind of search parameters

Currently the following information is retrieved in each call I perform to ebay servers.

My main question is: its possible to use elasticsearch as a key/value storage engine. where the value is the webservice response and the key is something like the relevant search parameters or the API call URL/XML in md5() format to hit the cache when a webuser request the same information?

any guideance, link or tutorial would be very appreciated, Im new in Elasticsarch. thank you.

You could use ES for this yes.

We have a number of clients that we provide to make it easy to interact with ES, so take a look [here](https://www.elastic.co/guide/en/elasticsearch/client/index.html) for something that you are comfortable with!

correct me please if Im wrong. the idea would be to create index a document providing an id with my query params. if the cache hits that query params retrieves body json fields information like the following example:

$params = [  
'index' =\> 'my\_index',  
'type' =\> 'my\_type',  
'id' =\> 'query-params',  
'timestamp' =\> strtotime("-1d"),  
'body' =\> ['testField' =\> 'abc', 'aspecthistograms' =\> 'abc', 'categoryhistograms' =\> 'abc']  
];

$response = $client-\>index($params);

etc...

thanks in advance. brgds!

Basically, yes.

You could do smart things like use an md5 hash of the query as the ID, then you can do things like routing - [https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-index\_.html#index-routing](https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-index_.html#index-routing)
