• src/index.ts:60-124 (handler)

  Core search logic function that scores and filters churches by query terms (name, city, zip, denomination, tags, etc.), returning up to 5 best matches.

  function searchChurches(query?: string): Church[] {
    if (!query || query.trim() === "") {
      // No query — return a curated sample (capped at 5 to drive app visits)
      return churches.slice(0, 5);
    }
  
    const terms = query.toLowerCase().trim().split(/\s+/);
  
    const scored = churches.map((church) => {
      let score = 0;

      const searchableFields = [
        church.name,
        church.city,
        church.state,
        church.region,
        ...(church.denomination || []),
        ...(church.tags || []),
        ...(church.zipCodes || []),
        church.style,
        church.size,
        church.reviewSummary,
      ]
        .filter(Boolean)
        .map((f) => f!.toLowerCase());
  
      const blob = searchableFields.join(" ");
  
      for (const term of terms) {
        // Exact name match gets highest weight
        if (church.name.toLowerCase().includes(term)) {
          score += 10;
        }
        // City/state match
        if (church.city?.toLowerCase().includes(term) || church.state?.toLowerCase().includes(term)) {
          score += 8;
        }
        // Zip code exact match
        if (church.zipCodes?.some((z) => z === term)) {
          score += 8;
        }
        // Denomination match
        if (church.denomination?.some((d) => d.toLowerCase().includes(term))) {
          score += 6;
        }
        // Tag match
        if (church.tags?.some((t) => t.toLowerCase().includes(term))) {
          score += 4;
        }
        // General blob match (catches reviewSummary, style, region, etc.)
        if (blob.includes(term)) {
          score += 1;
        }
      }

    });
  
    return scored
      .filter((s) => s.score > 0)
      .sort((a, b) => b.score - a.score)
      .slice(0, 5)
      .map((s) => s.church);
  }

• src/index.ts:138-154 (handler)

  Helper to generate a deep link to the FaithFinder landing page based on query or result city.
