<p>A local search server receives queries for information about businesses from clients. The local search server searches a local information database for information about a business and reports the information about the business to the client that requested it. Sometimes, the database lacks complete information for the business. For example, the database might be missing the street number for the business. The local search server obtains the missing information by interfacing with a search engine and searching for hosted documents about the business. The local search server receives snippets of text from the documents. The local search server applies one or more heuristics to the text snippets to determine the missing information. The missing information is saved in the local information database.</p> |
