Data searching device and method for data system

The invention relates to the technical field related to data systems, in particular to a data search device and method for a data system, and comprises a data search device and a data search method for the data system, and the data search device and method for the data system comprise a data search system, a big data search engine architecture and a data search branch thread. According to the data search device and method for the data system, a linear initialization code is executed, DOM event response is captured by a search engine, then a callback function is put into a queue and a callback queue, after the initialization code is executed, the search engine monitors a response event and sends a request, and after the initialization code is executed, the callback function is executed. According to the method, the callback function responding to the event is put into the queue to wait for execution, the callback function waiting for execution in the callback function is put into the queue ...
