|
||
<p>A prefilter refers to the idea of detecting candidate matches very quickly,
|
||
and then confirming whether those candidates are full matches. This
|
||
idea can be quite effective since it’s often the case that looking for
|
||
candidates can be a lot faster than running a complete substring search
|
||
over the entire input. Namely, looking for candidates can be done with
|
||
extremely fast vectorized code.</p>
|
||
<p>The downside of a prefilter is that it assumes false positives (which are
|
||
candidates generated by a prefilter that aren’t matches) are somewhat rare
|
||
relative to the frequency of full matches. That is, if a lot of false
|
||
positives are generated, then it’s possible for search time to be worse
|
||
than if the prefilter wasn’t enabled in the first place.</p>
|
||
<p>Another downside of a prefilter is that it can result in highly variable
|
||
performance, where some cases are extraordinarily fast and others aren’t.
|
||
Typically, variable performance isn’t a problem, but it may be for your use
|
||
case.</p>
|
||
<p>The use of prefilters in this implementation does use a heuristic to detect
|
||
when a prefilter might not be carrying its weight, and will dynamically
|
||
disable its use. Nevertheless, this configuration option gives callers
|
||
the ability to disable prefilters if you have knowledge that they won’t be
|
||
useful.</p>
