Alap v3 — Regex Search

Patterns are stored in config.searchPatterns and referenced with /key/ syntax. No inline regex in HTML — safe by design.

Basic: `/key/`

All bridges (string shorthand, searches all fields)

German cars (pattern: VW|BMW|Mercedes, label only)

searchPatterns: {
  bridges: 'bridge',                           // string shorthand
  german: { pattern: 'VW|BMW|Mercedes', options: { fields: 'l' } },
}

data-alap-linkitems="/bridges/"
data-alap-linkitems="/german/"

Field Options: `/key/opts`

Scenic spots (searches descriptions: fields: 'd')

Landmarks (searches tags: fields: 't')

Wikipedia links (searches URLs: fields: 'u')

German (override to tags) — expression /t overrides config's fields: 'l'

/scenic/     — config default: fields: 'd' (description)
/landmarks/  — config default: fields: 't' (tags)
/german/t    — expression overrides config to search tags instead of labels

Sorting & Limits

Bridges (A-Z) — sorted alphabetically by ID

Top 2 Bridges — limit: 2, sorted alpha

Recent (30 days) — items with createdAt within 30 days, newest first

alphaBridges: { pattern: 'bridge', options: { fields: 'l', sort: 'alpha' } }
topBridges:   { pattern: 'bridge', options: { fields: 'l', limit: 2, sort: 'alpha' } }
recent:       { pattern: '.', options: { age: '30d', sort: 'newest' } }

Composition with Operators

NYC bridges — regex AND class

Non-NYC bridges — regex WITHOUT class

German or Japanese — regex OR class

German cars, then coffee — regex comma-separated with class

NYC bridges or coffee — regex in parentheses

/bridges/ + .nyc          — AND: items matching "bridge" AND tagged "nyc"
/bridges/ - .nyc          — WITHOUT: "bridge" matches excluding "nyc"
/german/ | .japan         — OR: german regex results merged with .japan class
(/bridges/ + .nyc) | .coffee  — parenthesized grouping

Security

Patterns live in config, never in HTML attributes. The parser enforces: max 5 regex atoms per expression, 100 result cap, 20ms timeout. Invalid patterns return empty results silently.
