[FEATURE] Enhanced Search Functionality #3233
Description
Problem
Search is basic with advanced options hidden. For compliance users, search is the primary workflow but currently requires excessive navigation and only searches filenames.
Solution
Add three key capabilities:
1. Prebuilt Filters
Quick-access filters for:
- AI evidence
- Policy documents
- Expired evidence
- Unassigned evidence
2. Natural Language Search
Enable queries like:
- "Show me expired AI evidence from last quarter"
- "Find unassigned policy documents"
3. Metadata Search
Expand search beyond filenames to include:
- Tags, categories, assignees
- Dates (created, modified, expired)
- Custom metadata fields
Acceptance Criteria
- Prebuilt filters visible and combinable
- Natural language queries work for common compliance terms
- All metadata fields searchable
- Search respects user permissions
- Results indicate which field matched
