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.

Method to Update Archived Contact Information
The solution to above problem is by embedding a public key along with the email address in the document. Later if someone wants to change the email address, all they have to do is send an update message which includes the original email address and the both the old and new email addresses encrypted with the corresponding private key. The archive will search the documents for email addresses that match the original email address in the message and apply the public key to get the old and new email addresses. If they match, then it guarantees that the sender of this message was the original author and it is OK to trust them.
The following components would be required to implement our invention:
Archive Management Server
This server would handle requests to update address tags in the archive.
Archive Management Client This client will allow a user to specify the following pieces of information: - The original email address - The updated email address - Private key to encrypt these with - Name of the document to update - Hostname of the management server The client will then construct an update message containing the encrypted email addresses and the name of the document to update. This message will be sent to the management server.
One way for clients to locate archive management servers could be the DNS
