Multiple search terms including Keywords, Diseases and IPC Codes can be used simlutaneously searched with the operator 'or' ('and' is not supported). The corresponding help menu provides all the search terms available in the database and can be used to select existing search terms. Phrases or botanical names can be searched completely by enclosing in quotes, e.g. 'withania somnifera'.

This is a more precise and comprehensive search option. This option allow use of operator 'or'. A complete search query may contain at least five search terms simultaneously including Keywords/IPC Code/Title/Bibliographic Code/Disease, each individually specified.

TKRC (Traditional Knowledge Resource Classification) is designed to classify Indian Traditional Knowledge documentation. The TKRC contains language independent symbols and is modeled on the IPC. The various terms used have been put under different heads like plants, animals, diseases, actions, etc. The search can be used to familiarize oneself with this system of classification since the page also contains details of TKRC structure and allows search of various TKRC symbols from known terms.

The International Patent Classification (IPC) is a hierarchical system of symbols for the classification of patents and utility models based on different areas of technology of the patents. These symbols are language-independent and are used by more than 100 Patent offices and Regional offices for classification of their patent data. Only those IPC symbols relevant to TKDL are used and are from the 8th edition of the IPC. The appropriate IPC symbols may be selected from the IPC search menu provided. The IPC search allows for single or multiple symbols to be searched.
