|
|
|
|
**1. 3D tag** - matches `3D` optionally prefixed with `Bluray` or `BD`.
|
|
|
|
**2. Stereoscopic packing format** - matches Over-Under and Side-by-Side tags with an optional size prefix.
|
|
|
|
- The prefix group `(H(alf)?|F(ull)?)` recognises Half/H and Full/F as size indicators. The entire prefix is optional, so bare formats like `SBS` or `OU` match without one. Each optional suffix (`alf`, `ull`, `ver`, `nder`, `ide`, `y`) allows both short and long forms to match from a single pattern, e.g. `O(ver)?.?U(nder)?` matches `OU`, `Over.Under`, and mixed forms like `Over.U` or `O.Under`.
|
|
|
|
- Word boundaries `\b` at the start and end of the pattern prevent matches against substrings within larger words. For example, `HOURS` contains `OU` but has no word boundary between `O` and the preceding `H` or between `U` and the following `R`, so it does not match. Similarly `HOUSE` contains `HOU` but the trailing `SE` prevents a word boundary after `U`.
|
|
|
|
- Separators between components use `.?` (any single optional character) except between `S(ide)` and `B(y)` in the Side-by-Side pattern, which uses `[\W_]?` (non-word character or underscore). This is because `.?` would allow an alphabetic character in that position, causing false matches where a letter between S and B forms an unintended word. For example, `SOBS` would match as `S[O]B[]S` with `.?` consuming the O. Using `[\W_]?` restricts that position to only non-alphanumeric separators like dots, hyphens, spaces and underscores.
|
|
|
|
- Note that because the prefix is fully optional, double separators like `H..OU` or `Half..SBS` will still match. The prefixed path fails because `.?` only allows one separator character, but the engine falls back to matching bare `OU` or `SBS` at the end of the string where valid word boundaries exist.' where "name" = '3D' and "description" = 'Matches terms related to 3D video formats:

|
- `sbs` (side-by-side).
|
|
- `half ou` or `half sbs` with space (` `), dot (`.`), or hyphen (`-`) as separators.';
