Scoring notes

\n Matches at word boundaries (/, -, _, ., space) or camelCase\n transitions are favored with buffer scoring.\n
\n Adjacent matches implicitly gain weight as there are no buffer\n penalties between them.\n
\n Trailing unmatched characters are penalized; matches starting at\n index 0 are penalized less.\n
\n Timing shown is for scoring and sorting across all{\" \"}\n {paths.length.toLocaleString()} paths on each input change.\n
\n Type letters with spaces; spaces are ignored in matching to\n emulate Quicksilver behavior.\n

Scoring notes

\n Matches at word boundaries (/, -, _, ., space) or camelCase\n transitions are favored with buffer scoring.\n
\n Adjacent matches implicitly gain weight as there are no buffer\n penalties between them.\n
\n Trailing unmatched characters are penalized; matches starting at\n index 0 are penalized less.\n
\n Timing shown is for scoring and sorting across all{\" \"}\n {paths.length.toLocaleString()} paths on each input change.\n
\n Type letters with spaces; spaces are ignored in matching to\n emulate Quicksilver behavior.\n

Scoring notes

\n Matches at word boundaries (/, -, _, ., space) or camelCase\n transitions are favored with buffer scoring.\n
\n Adjacent matches implicitly gain weight as there are no buffer\n penalties between them.\n
\n Trailing unmatched characters are penalized; matches starting at\n index 0 are penalized less.\n
\n Timing shown is for scoring and sorting across all{\" \"}\n {paths.length.toLocaleString()} paths on each input change.\n
\n Type letters with spaces; spaces are ignored in matching to\n emulate Quicksilver behavior.\n

Scoring notes

\n Matches at word boundaries (/, -, _, ., space) or camelCase\n transitions are favored with buffer scoring.\n
\n Adjacent matches implicitly gain weight as there are no buffer\n penalties between them.\n
\n Trailing unmatched characters are penalized; matches starting at\n index 0 are penalized less.\n
\n Timing shown is for scoring and sorting across all{\" \"}\n {paths.length.toLocaleString()} paths on each input change.\n
\n Type letters with spaces; spaces are ignored in matching to\n emulate Quicksilver behavior.\n

Scoring notes

\n Matches at word boundaries (/, -, _, ., space) or camelCase transitions are favored with buffer scoring.\n
Adjacent matches implicitly gain weight as there are no buffer penalties between them.
Trailing unmatched characters are penalized; matches starting at index 0 are penalized less.
\n Timing shown is for scoring and sorting across all {paths.length.toLocaleString()}{\" \"}\n paths on each input change.\n
Type letters with spaces; spaces are ignored in matching to emulate Quicksilver behavior.
