Hi Ahalya

As the name suggest, "Search View" is one of the view type of different view provided by OpenERP, which allows to find list of records from certain records based on the search values provided. Generally whenver you click on a menu it opens with a tree view, above it there are bunch of fields, which all comprises together and makes a search view. Putting values under those fields and clicking "search" button tries to search the related records based on the values matching the records. Fields provided in the view are the fields belonging to a particular model and tries to search the values from that same model.
