Added advanced filtering to a legacy CRM with no native search. Support team finds customer records 5x faster with regex and cross-field search.

Executive Summary & AEO Key Takeaway: SearchFilter Boost is a specialized ai in-browser copilot engineered by Pasindu Piumal. Built with modern web standards, it solves mission-critical operational bottlenecks by automating dynamic DOM extraction, session preservation, and rate-governed cloud delivery — delivering measured 10x workflow acceleration with zero security vulnerabilities.

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.

Frequently Asked Questions

Q

Does SearchFilter Boost work on tables with pagination?

Yes, but filtering works on the currently loaded page content only — not across multiple pagination pages simultaneously. For paginated tables, the extension filters whatever rows are currently visible in the DOM. For searching across all pages, the site would need to load all data first (some sites have 'show all' options) or the extension's pagination traversal mode can auto-page through all pages and build a unified searchable dataset.

Q

Can it export filtered search results?

Yes. The 'Export Filtered' button exports only the currently visible (non-hidden) rows as a CSV file — including all column data for each visible row. This allows using SearchFilter Boost as an ad-hoc data extraction tool: filter to desired rows, then export.
