摘要
In the field of computer text search engines, regular expression text pattern matching is combined with an extended set of Boolean operators. A pre-processor is described which will convert mixed Boolean-GREP expressions into equivalent pure GREP expressions enabling existing GREP search technology to be used to implement this invention. Additional optimizations are described when users need to search for any one of a list of text patterns.
