Current state of the art of Markush topological search systems ?
A comparative analysis of the two major Markush search capabilities online, Markush DARC (MDARC) and MARPAT, is presented. The analysis, illustrated by reference to specific examples, provides detailed comments under the broad headings of database content, system issues, display issues, and costs. Database content issues discussed include indexing very broad or vague claims, the backlog position, the increasing volume of data, and timeliness. System issues discussed include translation capability, variable ring nodes, ring isolation, alkyl chain (Ak) definition, search engine speed, search software, and query construction. The article concludes by emphasizing the need for searchers in this field to carry out comprehensive searches, sometimes involving use of both of these systems, as well as using fragmentation code systems, etc., and the corresponding need for the software to be improved, especially in the display function
