Concept Search - What can I type?
For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.
Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.
By widening the vertical scrollbar and enabling the cursor to move horizontally, you can scroll the window freely to every direction without swithing the cursors from vertical scrollbar to horizontal one.

A wide vertical scrollbar enabling horizontal scroll
1. Problem of the current scrollbars
When you read a large document on GUI system such as Windows®, you use a cursor on
a scrollbar to scroll it. (Windows is a registered trademark of Microsoft Corporation in the
United States and/or other countries.)
When the document is longer than the window, a vertical scrollbar appears at the right
hand side of the window. When the document is wider, a horizontal scrollbar appears at
the bottom of the window. By holding and moving the cursor on the scrollbar, you can
scroll the area that appears in the window.
In this way you can choose and show any part of the large document on the window, but
you need to handle the two cursors, one on the vertical scrollbar and one on the
horizontal scrollbar, which is often inconvenient when you read the document vertically
long, but not so wide. Reading such document you often scroll up and down and rarely
move horizontally, but once horizontal scroll becomes necessary, you have to take the
vertical cursor off and go to the bottom of the window, hold the horizontal cursor and
handle it, and after that you have to go back to the vertical one.
Picture 1. You have to go to the bottom to scroll the document right
2. Solution given by this invention
Here I propose to widen the vertical scrollbar keeping the width of the cursor and to
enable it move horizontally on the vertical scrollbar. In this way you can scroll the
document in every direction by holding a cursor.

The width of the scrollbar is calculated as:
the original width of the scrollbar * the width of the document / the width of document
shown in the window
In this way, we keep the ratio of the width of the scrollbar to the width of the cursor
same as that of horizontal scrollbar. So when you put the cursor at the right end
