This OCaml library implements the Wu-Manber algorithm for string searching
with errors, popularized by the "agrep" Unix command and the "glimpse" file
indexing tool. It was developed as part of a search engine for a largish MP3
collection; the "with error" searching comes handy for those who can't spell
Liszt or Shostakovitch.
.
Given a search pattern and a string, this algorithm determines whether the
string contains a substring that matches the pattern up to a parameterizable
number N of "errors". An "error" is either a substitution (replace a
character of the string with another character), a deletion (remove a
character) or an insertion (add a character to the string). In more
scientific terms, the number of errors is the Levenshtein edit distance
between the pattern and the matched substring.
.
The search patterns are roughly those of the Unix shell, including
one-character wildcard (?), character classes ([0-9]) and multi-character
wildcard (*). In addition, conjunction (&) and alternative (|) are supported.
General regular expressions are not supported, however.
.
This package contains only the shared runtime stub libraries.
