The program searches among the symptoms of a medical database, so the results will only be medical afflictions. There are about 1,800 afflictions in the database, so no matter how deep the search depth and how many symptoms are entered, there will be at most about 1,800 results. The links from the results page point to affliction pages which are either public domain government pages or GNU Free Documentation License pages.
The greatest advantage of the diagnotep search engine is that it searches only medical affliction pages, so the results are not cluttered with pages which are not about health. Another advantage is that the program searches only the symptom part of the affliction pages, so the results are not cluttered with unrelated medical pages. The greatest disadvantage of diagnotep is that it searches a medical database which is large, but incomplete; it does not include all the medical pages on the internet. Another disadvantage is that diagnotep has a size of about 200 kilobytes and so takes about 30 seconds to load on a 56k dialup modem.
Diagnotep development is ongoing and in the future it is hoped that there will be expanded treatment sections for common afflictions, that more afflictions will be added to the medical database and that the 200 kB size of the diagnotep script will be reduced for faster loading.
