Hi all,
i am a master's student. I have to do a keyword search for spatial
database. I have the data set of a particular district in India. I
have a data model too.
Can some one help me through this task.

My question is - it is a single word (keyword) search. I have the
database schema too. How do i search this keyword through this schema
or the entire data. How do i convert this keyword into a sql query
that the database system would understand and query the database.
Eg keyword- river.

I would appreciate advice.
TIA.
