Claim 18:
19. A system to perform text-based search among a plurality of documents, wherein each document comprises text having at least one reference-identifier, the system comprising:
a database having the plurality of documents; and
a server arrangement configured to:
(i) receive a starting document having at least one reference-identifier associated with the document,
(ii) select a reference-text from the starting document,
(iii) generate a search-string by using:
a plurality of keywords selected from the reference-text using at least one first machine learning algorithm, and
at least one search-operator derived for the plurality of keywords using at least one second machine learning algorithm,

(iv) perform a search among the plurality of documents using the search-string to fetch a set of documents,
(v) determine a number of relevant documents in each of the set of documents;
(vi) derive a reference-identifier distribution for the number of relevant documents, wherein each of the number of relevant documents has at least one reference-identifier associated therewith; and
(vii) correlate the at least one reference-identifier associated with the starting document with the reference-identifier distribution to determine a performance-score for the system, wherein at least the steps (iii) to (vii) are performed iteratively until the performance-score exceeds a predetermined threshold, wherein at each iteration a different search-string is generated at the step (iii).
