Executive Summary & Commercial Scope

SearchFilter Boost is a universal search and filter enhancement extension engineered by Pasindu Piumal for a customer support team on Fiverr using a legacy CRM with minimal search capabilities. The team was manually scrolling through long tables to find records because the CRM only supported basic exact-match search. The extension adds a floating search bar to any website with instant regex-capable cross-field filtering, result highlighting, and saved presets.

1. Non-Destructive DOM Filtering

The extension hides non-matching rows using display:none rather than removing them from the DOM — preserving all React/Vue component state and any event listeners attached to hidden rows. This means filtering works correctly on dynamic tables without breaking pagination, row click handlers, or data-bound properties.

2. Regex-Powered Cross-Field Search

Advanced search syntax supports: exact phrase ("exact phrase"), regex mode (/pattern/flags), column-specific search (col:email=@gmail), exclusion (-keyword), and OR combinations (term1|term2). This transforms a legacy application's basic search into a developer-grade filtering tool.

3. Persistent Per-Domain Filter Presets

Filter presets (saved filter configurations) are stored per domain in chrome.storage.sync — so presets configured on the legacy CRM at crm.company.com are available on all browsers where the user is signed in. Each preset stores the filter expression, active columns, and regex/case flags — restoring the complete filter state in one click.

4. Memory-Optimized Batch Ingestion & Deduplication

Bulk scraping workloads process tens of thousands of records that can quickly exhaust browser memory. The extraction worker streams data through a persistent indexed deduplication buffer, pruning redundant records in real time and buffering batches directly to disk or cloud destinations to maintain a lightweight, zero-leak memory footprint.
