Search a string using a web search engine like query

This code demonstrates how to search a string using a web search engine style query. With this code you can analyze text files looking for specific patterns. For example: (Microsoft and AOL) or "instant messenger" This query will analyze any string for the occurrence of the words Microsoft and AOL or "instant messenger". I use this code (in conjunction with other code) to scan the users hard drive for occurrences of text files that meet the user defined search parameters. This is an enhanced version of the search for files containing text feature in windows.
