METHOD AND SYSTEM TO PERFORM TEXT-BASED SEARCH AMONG PLURALITY OF DOCUMENTS

A method for training system to perform text-based search among plurality of documents. The method including receiving starting document, having at least one reference-identifier associated with the document; selecting reference-text from starting document; generating search-string by using a plurality of keywords using at least one first machine learning algorithm and at least one search-operator using at least one second machine learning algorithm; performing search among plurality of documents using search-string to fetch set of relevant documents; deriving reference-identifier distribution, corresponding to the at least one reference-identifier associated with document, for the set of relevant documents; and corelating at least one reference-identifier associated with starting document with reference-identifier distribution to determine performance-score for system. The steps of method are iteratively performed until performance-score exceeds a predetermined threshold, wherein at each iteration at least one of: different search-string is generated, different reference-text is obtained, different document is received.
