Abstract: A system and a method for conducting spatio-temporal search using crowd source based real-time database are provided. The method may include: receiving from an inquiring user a combination of user related data (URD) related to at least one real time event, comprising at least one of: a temporal data, a spatial data and a contextual filter; generating a tempo-spatial contextual query based on the received URD; storing tempo-spatial contextual (TSC) data received from a crowd of users over a computerized network wherein said TSC is indicative of real time events; applying said query to said real time database for retrieving TSC data relevant to said query, wherein said search engine utilizes real time ranking from said crowd of users in applying the query; and presenting the relevant TSC data to the inquiring user.
