Hi, I need to know how does the search works. The index of Catalog is made based in a pythonMethod that returns an concatenated text with the contents of a lot of fields I made an external method in python that do the search and sort the entire result. It´s an priorized sort, that i need to priorize the keywords, so the results that have the searched text in the keywords list will be showed first. I made the sort by dividing the resuilts in two secondaries lists, one that contains the results with searched text in the keywords and the another that does not. finaly I return the two lists concatenated. I need to know if there is a better way to do the priorized search in many fields and if the solution that I made will "destroy" the server´s memory and/or cpu. If possible, i want to know how the ZsearchInterface works internally.. Thanks.. Srinath M.
