Let us explore the document search features first. Instead of using keyword(s) in a document search query, you can input a sentence or a whole paragraph (using cut-n-paste from an article) into the query box (Fig. 3). Alternatively, you can use the advance search page to control your query. Most search engines cannot support such complex input. You can even find the closest match of a predefined document of your choice. You can perform a search for the particular document that you have uploaded and when that document is retrieved, click on “related document” and you will find a list of related documents ranked in term of relevancy to the document in context. This kind of keyword matching document retrieval is called syntactical search (keyword search). In here, ANTOM provides relevancy ranking which is only found in advance search systems.
