Advanced Text Search & Matching

Production-grade text search algorithms for finding and matching text in large documents with millisecond performance. Includes Boyer-Moore search, n-gram similarity, fuzzy matching, and intelligent indexing.

When to use this skill

• Building search features for large documents or transcripts
• Finding quotes or citations in text with imperfect matches
• Implementing fuzzy search that handles typos and variations
• Need character-level precision for highlighting
• Building citation systems or source verification
• Searching across segmented content (chapters, timestamps, etc.)
• Performance-critical text matching (100k+ character documents)
