Traditional Search Filters – UI Mix P-sense search UI
Current / traditional property search filters are isolated and requires multiple clicks. Very few % of people using these filters
across the UI. Therefore their relevance in property search & UI personalization become complex. P-sense does this all in one
funnel by understanding the majority of property variables from open text search.
