BluePrint: Text Search

Introduction

The Blueprint outlines the development of two functionalities for Sahana Eden. They are:

Full-text Search

• It will provides users to search for text in uploaded documents.

Global Search

• It will provide users to search for text over multiple resources (eg. Organization, Hospital, etc.).

Stakeholders

• The End Users
  

Agencies like:

• TLDRMP : Timor Leste Disaster Risk Management Portal
• CSN : Community Stakeholder Network
• LAC: Los Angeles County
• IFRC : International Federation of Red Cross and Red Crescent Societies

User Stories

For Full-Text Search:

• The user will have to go to Document module and Search option. Then he has to type the text(or the specified query format) to search in all the uploaded documents.
• The result will be the name on the document, the link to the uploaded documents(specifying the authorization checks) and a line of text containing the search string.
