Matching Algorithm

The chatbot uses a multi-layered matching algorithm:

1. Exact Keyword Matching (+30 points per match)
2. Fuzzy Matching with Levenshtein distance (+20 points)
3. Bigram Matching (+10 points per match)
4. Overall Similarity with similar_text (+25 points max)
5. Word Matches (+5 points per word)

Thresholds:

• ≥ 80 points: Very confident match (direct answer)
• 60-79 points: Probable match (answer with alternatives)
• < 60 points: No match (contact form)
