Thanks. Currently I am also referring to different implementations of an index to see the most suitable to implement. For an R+ tree ( a variant of R tree ), I have found an example implementation in C. Does anyone know of an R+ tree implementation done with GIST (generalized search tree)? Since a GIST structure is also available in Postgresql.
Thanks again.
