| <p>There are two generally different ways that Aho-Corasick automatons can |
| report matches. The first way is the “standard” approach that results from |
| implementing most textbook explanations of Aho-Corasick. The second way is |
| to report only the leftmost non-overlapping matches. The leftmost approach |
| is in turn split into two different ways of resolving ambiguous matches: |
| leftmost-first and leftmost-longest.</p> |
| <p>The <code>Standard</code> match kind is the default and is the only one that supports |
| overlapping matches and stream searching. (Trying to find overlapping or |
| streaming matches using leftmost match semantics will result in an error in |
| fallible APIs and a panic when using infallibe APIs.) The <code>Standard</code> match |
| kind will report matches as they are seen. When searching for overlapping |
| matches, then all possible matches are reported. When searching for |
| non-overlapping matches, the first match seen is reported. For example, for |
| non-overlapping matches, given the patterns <code>abcd</code> and <code>b</code> and the haystack |
| <code>abcdef</code>, only a match for <code>b</code> is reported since it is detected first. The |
| <code>abcd</code> match is never reported since it overlaps with the <code>b</code> match.</p> |
| <p>In contrast, the leftmost match kind always prefers the leftmost match |
| among all possible matches. Given the same example as above with <code>abcd</code> and |
| <code>b</code> as patterns and <code>abcdef</code> as the haystack, the leftmost match is <code>abcd</code> |
| since it begins before the <code>b</code> match, even though the <code>b</code> match is detected |
| before the <code>abcd</code> match. In this case, the <code>b</code> match is not reported at all |
| since it overlaps with the <code>abcd</code> match.</p> |
| <p>The difference between leftmost-first and leftmost-longest is in how they |
| resolve ambiguous matches when there are multiple leftmost matches to |
| choose from. Leftmost-first always chooses the pattern that was provided |
| earliest, where as leftmost-longest always chooses the longest matching |
| pattern. For example, given the patterns <code>a</code> and <code>ab</code> and the subject |
| string <code>ab</code>, the leftmost-first match is <code>a</code> but the leftmost-longest match |
| is <code>ab</code>. Conversely, if the patterns were given in reverse order, i.e., |
| <code>ab</code> and <code>a</code>, then both the leftmost-first and leftmost-longest matches |
| would be <code>ab</code>. Stated differently, the leftmost-first match depends on the |
| order in which the patterns were given to the Aho-Corasick automaton. |
| Because of that, when leftmost-first matching is used, if a pattern <code>A</code> |
| that appears before a pattern <code>B</code> is a prefix of <code>B</code>, then it is impossible |
| to ever observe a match of <code>B</code>.</p> |
| <p>If you’re not sure which match kind to pick, then stick with the standard |
| kind, which is the default. In particular, if you need overlapping or |
| streaming matches, then you <em>must</em> use the standard kind. The leftmost |
| kinds are useful in specific circumstances. For example, leftmost-first can |
| be very useful as a way to implement match priority based on the order of |
| patterns given and leftmost-longest can be useful for dictionary searching |
| such that only the longest matching words are reported.</p> |
| <h2 id="relationship-with-regular-expression-alternations"><a href="#relationship-with-regular-expression-alternations">Relationship with regular expression alternations</a></h2> |
| <p>Understanding match semantics can be a little tricky, and one easy way |
| to conceptualize non-overlapping matches from an Aho-Corasick automaton |
| is to think about them as a simple alternation of literals in a regular |
| expression. For example, let’s say we wanted to match the strings |
| <code>Sam</code> and <code>Samwise</code>, which would turn into the regex <code>Sam|Samwise</code>. It |
| turns out that regular expression engines have two different ways of |
| matching this alternation. The first way, leftmost-longest, is commonly |
| found in POSIX compatible implementations of regular expressions (such as |
| <code>grep</code>). The second way, leftmost-first, is commonly found in backtracking |
| implementations such as Perl. (Some regex engines, such as RE2 and Rust’s |
| regex engine do not use backtracking, but still implement leftmost-first |
| semantics in an effort to match the behavior of dominant backtracking |
| regex engines such as those found in Perl, Ruby, Python, Javascript and |
| PHP.)</p> |
| <p>That is, when matching <code>Sam|Samwise</code> against <code>Samwise</code>, a POSIX regex |
| will match <code>Samwise</code> because it is the longest possible match, but a |
| Perl-like regex will match <code>Sam</code> since it appears earlier in the |
| alternation. Indeed, the regex <code>Sam|Samwise</code> in a Perl-like regex engine |
| will never match <code>Samwise</code> since <code>Sam</code> will always have higher priority. |
| Conversely, matching the regex <code>Samwise|Sam</code> against <code>Samwise</code> will lead to |
| a match of <code>Samwise</code> in both POSIX and Perl-like regexes since <code>Samwise</code> is |
| still longest match, but it also appears earlier than <code>Sam</code>.</p> |
| <p>The “standard” match semantics of Aho-Corasick generally don’t correspond |
| to the match semantics of any large group of regex implementations, so |
| there’s no direct analogy that can be made here. Standard match semantics |
| are generally useful for overlapping matches, or if you just want to see |
| matches as they are detected.</p> |
| <p>The main conclusion to draw from this section is that the match semantics |
| can be tweaked to precisely match either Perl-like regex alternations or |
| POSIX regex alternations.</p> |
