Spatio-Textual technology: The future of web search

This study was developed believing that geographic search technology is the future of research methodology. Due to the importance of geographical environment in the routine issues, the close connection between spatial extension and most of the phenomena running over the world, the geographic query process turns to be key factor in overcoming hazard decision-making and evaluation. Spatial research differs in that it requires a combination of text and geographical data. To find the right formula we need to adapt the search algorithm to the application needs. We take note the Earth is nearly spherical (ignoring ellipsoidal effects) so great-circle distance formulas give the distance between points on the surface of the Earth correct to within 0.5% or so [5]. According to the search range and the search limit we induce to introduce the Cosine algorithm who better fulfill the two basic requirements, speed performance and data retrieval accuracy.
