Advanced Search

The Advanced Search Page allows you to make a query to search the China TCM Patent Database using command line search syntax.

There are 3 steps to submit a query using the Advanced Search Page:
1. Select a year or scope of years to search in the Select Years Entry box. There are three time selections in the pull-down menu: (a) Application year; (b) Publication year; (c) Database update year. Default selection year is "Application year" and the default time scope covers all data in the database.
2.Type your search statement into the Query box.
3. Press the Search button.
Note:
1.The search is not case-sensitive. Searching for Hypertension and searching for hypertension will produce same results.
2. If you use field code to limit your search terms, you must specify the field by a suffix after the search term to get the hits you expect, e.g. huang zhiyuan/PA
The advanced search features:
Nested Boolean Expressions
Field Searching
Phrase Searching

--------------------------------------------------------------------------------------------------------------------

Nested Boolean Expressions
You can use the Advanced Search Page to create and execute Boolean searches with more than two search terms/phrases that use the Boolean operators (OR, AND, NOT). Along with these operators, you can use parentheses to further clarify your search statement. In the absence of parentheses, all operators associate from left to right.
Example 1
Radix ginseng AND (hypertension OR vascular)
If you enter this query, you will retrieve a list of all patents which contains both "radix ginseng" and either "hypertension" or "vascular" somewhere in the document.
Example 2
hypertension OR (radix ginseng AND rhubarb)
This query would return patents containing either the word "hypertension" OR both "radix ginseng" AND "rhubarb".
Example 3
hypertension NOT (radix ginseng OR rhubarb)
This complex query generates a list of hits that contain the word "hypertension", but do not contain any references containing "radix ginseng" OR "rhubarb".

--------------------------------------------------------------------------------------------------------------------
Field Searching
The Advanced Search Page allows you to search individual fields found within patents. You can find a list of all indexed fields in the table under the query box of the page. The full names for each field are given on the right of the column and the corresponding field code is listed on the left.
To narrow your search to hits occurring within a single field, add a suffix with the field code after your search term followed by a forward slash (/). If you do not select a specific field, the text of the entire patent will be searched. If you need help with field searching, see the Field Searching Help Page.
Example 1
sun/INR
This will search for the word sun within the Inventors Name field of the database. Occurrences of the search term anywhere else on the front page will be ignored.
Example 2
A61k035/78/IC1
This query searches for the Main IPC A61k035/78, and will return a list of all patents assigned to that class.
Example 3
xie xiuqiong/INR AND hypertension/TI
As this example demonstrates, you can mix field searching with Boolean searching. This query would retrieve a list of hits which contain sun in the Inventors Name field, and the word hypertension in the Patent Title.

--------------------------------------------------------------------------------------------------------------------
Phrase Searching
A group of words will be treated as a single search term. This allows you to search for a multi-word phrase rather than specifying each word as a separate term. If multi phrases appeare in one search query, logic operators must be used to separate different phrases.
Example 1
Herba Calthae
Searching on this phrase would return a list of all the patents which have the phrase Herba Calthae anywhere within the indexed text.
Example 2
Bulbus Lilii and (Radix Bupleuri Radix OR Paeoniae Alba OR Semen Ziziphi Spinosae)
Searching on this query would return a list of all the patents which contain the phrases "Bulbus Lilii" and (Radix Bupleuri Radix OR Paeoniae Alba OR Semen Ziziphi Spinosae) anywhere within the indexed text
Example 3
zhao guoxin/INR
This query would find all occurrences of the phrase zhao guoxin within the Applicant field.

Examples
To search all the patent related to Radix Paeoniae Alba and Rhizoma Pinelliael or Poria to cure hypertension.
