An improved system and method for string processing and searching using a compressed permuterm index is provided. To build a compressed permuterm index for a string dictionary, an index builder constructs a unique string from a collection of strings of a dictionary sorted in lexicographic order and then builds a compressed permuterm index to support queries over the unique string. A dictionary query engine supports several types of wild-card queries over the string dictionary by performing a backward search modified with a CyclicLF operation over the compressed permuterm index. These queries may used to implement other queries including a membership query, a prefix query, a suffix query, a prefix-suffix query, a query for an exact or substring match, a rank query, a select query and so forth. String processing and searching tasks may accurately be performed for sophisticated queries in optimal time and compressed space.

In one embodiment, a method for correlating log entries in a log file to the line numbers of formatted-string output functions in source code, where the formatted-string output functions contain instructions to generate the log entries in the log file. The method includes locating the formatted-string output functions in the source code, where each formatted-string output function contains a format string. Each format string is processed to generate a corresponding regular expression to match log entries outputted by the corresponding formatted-string output function. Each regular expression is associated with the line number of the corresponding formatted-string output function. The resultant list of regular expressions and corresponding line numbers is processed with the log file, where log entries in the log file are modified to indicate the line numbers associated with matching regular expressions.
