[[TOC]]

== 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[[BR]]
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:
[[BR]]
*    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.

== Requirements ==
=== Functional ===
For Full Text Search:[[BR]]
*    Proper understanding and the work model of S3Search(depricated) and S3Filter is required.

*    Literature study of Apache Lucene and PyLucene.

*    Getting familiar with '''PyLucene''' and deploy it into my local machine.

*    Studying the linkage of the Lucene daemon and web2py server.

*    Extend the functionality of S3Filter by introducing an addition feature (which is a text field) to search for text through documents.

* 
 
=== Non-functional ===
=== Standards ===
=== System Constraints ===
* The user should have PyLucene installed in there machine.
* Also, while starting the web2py server, the Lucence deamon should also start.
* In case of failure, the search query related to full-text search will not be functional.
