+# Filter Panel Testing Guide
+
+## Testing Both Pages
+
+The filtering system is now available on **two pages**:
+1. **Index page** (`docs/index.html`) - Community card grid
+2. **UMAP page** (`docs/community_umap.html`) - Interactive visualization
+
+Both pages share the same filtering UI and behavior.
+
+## Manual Testing Checklist for Both Pages
+
+### 1. Enhanced Search Functionality
+- [ ] Open `docs/community_umap.html` in browser
+- [ ] Type "AMD" in search box → should highlight ~8 AMD communities
+- [ ] Type "Richmond" → should show 1 community (Richmond Mine)
+- [ ] Type "acid" → should match environment field and show relevant communities
+- [ ] Click clear button (✕) → should reset search and show all 73 communities
+- [ ] Search counter should update: "Showing X of 73 communities"
+
+### 2. Category Facet
+- [ ] Check "AMD" checkbox → should filter to ~8 AMD communities
+- [ ] Check both "AMD" and "DIET" → should show both categories (OR logic)
+- [ ] Click "All" button → should check all 14 category boxes
+- [ ] Click "None" button → should uncheck all boxes
+- [ ] Counts should update dynamically: "AMD (8)", "DIET (6)", etc.
+
+### 3. Ecological State Facet
+- [ ] Check "STABLE" → should filter to stable communities
+- [ ] Check "ENGINEERED" → should add engineered communities to filter
+- [ ] Uncheck boxes → should update visualization immediately
+
+### 4. Origin Facet
+- [ ] Check "NATURAL" → should filter to natural communities
+- [ ] Check "SYNTHETIC" → should add synthetic communities
+- [ ] Multiple selections should work (OR logic)
+
+### 5. Combined Filters (AND logic between facet types)
+- [ ] Search "iron" + check "AMD" → should show intersection
+- [ ] Search + Category + State → should combine all filters
+- [ ] Filtered points should fade to opacity 0.1
+- [ ] Visible points should remain at opacity 0.8
+
+### 6. Active Filters Summary
+- [ ] Apply any filter → yellow "Active Filters" box should appear
+- [ ] Should show removable tags: "Search: term", "Category: AMD", etc.
+- [ ] Click ✕ on tag → should remove that specific filter
+- [ ] Click "Clear All" button → should reset all filters
+- [ ] Summary should hide when no filters active
+
+### 7. Zoom/Pan Preservation
+- [ ] Apply filter → zoom in → change filter
+- [ ] Verify zoom level is preserved (no reset to default view)
+- [ ] Pan to different area → apply filter → verify pan preserved
+
+### 8. Facet Collapse/Expand
+- [ ] Click on "Category" header → should collapse facet (show + icon)
+- [ ] Click again → should expand facet (show − icon)
+- [ ] Same for "Ecological State" and "Origin" facets
+
+### 9. Responsive Layout
+- [ ] Resize browser to < 1200px width
+- [ ] Filter panel should move above plot (vertical stacking)
+- [ ] All functionality should still work
+
+### 10. Color/Size Controls Compatibility
+- [ ] Change "Color by" dropdown → filters should persist
+- [ ] Change "Size by" dropdown → filters should persist
+- [ ] Filtered state should be maintained after visualization updates
+
+### 11. Performance
+- [ ] Typing in search should have ~150ms debounce (smooth, no lag)
+- [ ] Checking/unchecking facets should update instantly
+- [ ] No JavaScript errors in browser console (F12)
+
+### 12. Counts and Statistics
+- [ ] Initial load: "Showing 73 of 73 communities"
+- [ ] After filtering: counts should accurately reflect visible communities
+- [ ] Facet counts should update based on current filter state
+- [ ] All counts should be consistent and accurate
+
+## Browser Compatibility
+Test in:
+- [ ] Chrome/Edge (Chromium)
+- [ ] Firefox
+- [ ] Safari
+
+## Expected Results Summary
+
+### UMAP Page (`community_umap.html`)
+
+**Initial State:**
+- 73 communities visible as points
+- All facets expanded with counts
+- No active filters
+- Search bar empty
+
+**After Filtering:**
+- Filtered points at opacity 0.1 (nearly invisible)
+- Visible points at opacity 0.8 (normal)
+- Active filters summary visible with yellow background
+- Dynamic count updates
+- Removable filter tags
+- Zoom/pan state preserved
+
+### Index Page (`index.html`)
+
+**Initial State:**
+- 82 community cards visible in grid
+- All facets expanded with counts
+- No active filters
+- Search bar empty
+
+**After Filtering:**
+- Filtered cards completely hidden (display: none)
+- Visible cards remain in grid
+- Active filters summary visible with yellow background
+- Dynamic count updates
+- Removable filter tags
+- Grid layout adjusts dynamically
+
+**User Experience (Both Pages):**
+- Smooth, responsive filtering
+- No page reloads
+- Clear visual feedback
+- Intuitive controls
+- Consistent UI across both pages

+# 🎉 Enhanced Search and Filtering - Complete!
+
+## What Was Built
+
+Successfully implemented comprehensive filtering systems for **BOTH** pages:
+
+### 1. 📇 Index Page (`docs/index.html`)
+**Before:** Simple card grid, no filtering
+**After:** Full filtering with search and category facets
+
+✅ **Enhanced Search**
+- Searches name AND description fields
+- 150ms debounce for smooth typing
+- Clear button (✕) to reset
+- Results counter: "Showing X of 82 communities"
+
+✅ **Category Facet**
+- 14 checkboxes (AMD, BIOMINING, DIET, etc.)
+- Dynamic counts: "AMD (8)", "SYNTROPHY (6)", etc.
+- "Select All" / "Clear All" buttons
+- Sorted by count (descending)
+
+✅ **Ecological State Facet**
+- 3 checkboxes: STABLE, PERTURBED, ENGINEERED
+- Dynamic counts per state
+
+✅ **Active Filters Summary**
+- Yellow box showing all active filters
+- Removable tags with ✕ button
+- "Clear All" button
+
+✅ **Filtering Behavior**
+- Filtered cards completely hidden
+- Grid adjusts dynamically
+- AND logic between facets
+- OR logic within facets
+
+### 2. 📊 UMAP Page (`docs/community_umap.html`)
+**Before:** Simple name/ID search only
+**After:** Full filtering with multi-field search and facets
+
+✅ **Enhanced Search**
