Managed search change governance that coordinates indexing updates with promotion and reporting workflows.
Best for: Fits when enterprises need managed ecommerce search integration and controlled change governance.
Globant
Editor pickSearch implementation tied to commerce and analytics engineering, with structured automation for catalog-driven updates.
Best for: Fits when commerce engineering needs governed search integration during modernization or rollout.
Cognizant

Comparison Table
Capgemini
agencyConsultancy delivering commerce and search solutions.
Managed search change governance that coordinates indexing updates with promotion and reporting workflows.
Capgemini fits ecommerce site search work that needs more than a widget because engagements typically span multiple systems and ongoing change management. Integration depth shows up in catalog indexing and production pipeline connections that keep search results aligned with catalog and merchandising inputs. Administration and governance focus appears in controlled rollout patterns and role based distribution of search related outputs, which supports auditability for enterprise stakeholders.
A tradeoff appears when the organization expects a fully self serve setup with minimal service involvement, since Capgemini engagements emphasize implementation and operational management. Capgemini works best for usage situations where search changes must reflect trade promotion scenarios, recurring KPI reporting, and tender cycle deliverables that require consistent inputs across teams.
- +Governed rollout of search changes for enterprise stakeholders
- +Implementation support that connects search to commerce and data workflows
- +Recurring reporting alignment for search impact and KPI consistency
- +Scenario planning support that ties search behavior to promotions
- –Less suitable for teams wanting a self serve-only deployment
- –Search improvements depend on structured merchandising and governance inputs
- –Longer delivery timelines when integrating many upstream systems
- –Requires disciplined ownership of catalogs and performance refresh cadence

Best for: Fits when enterprises need managed ecommerce search integration and controlled change governance.
Globant
agencyDigital consultancy with commerce search services.
Search implementation tied to commerce and analytics engineering, with structured automation for catalog-driven updates.
Globant is a strong choice for ecommerce site search when search has to connect to the broader catalog ingestion and merchandising logic, not just render results. Engineering support covers implementation of search experience surfaces used by shoppers, plus integration plumbing that keeps indexing aligned with upstream product data flows. Automation and API integration matter most for teams that need predictable updates and controlled release coordination across environments.
A practical tradeoff appears when governance and operational controls are expected to run fully in-house, since Globalent’s work still relies on client-side ownership of data readiness and merchandising rules. Globant fits well for ecommerce organizations that need phased modernization of front-end and back-end capabilities while keeping search behavior stable during rollout.
- +Engineering delivery pairs search integration with commerce experience workstreams
- +API-focused approach supports controlled provisioning across environments
- +Automation emphasis helps keep indexing and search behavior aligned to releases
- +Analytics-informed implementation supports measurable improvements to on-site search outcomes
- –Requires strong client data readiness for catalog changes and indexing timeliness
- –Governance expectations increase implementation overhead for small teams

Cognizant
agencyDigital consultancy with commerce search services.
Enterprise governance and lifecycle support wrapped around search integration and operational monitoring, not a standalone site widget.
Cognizant fits ecommerce organizations that need search tied to upstream data flows, since its delivery motion aligns with enterprise integration and operational governance work. Cognizant is also well suited when ecommerce search must support traceable metrics across CRM, contact center, and web channels for journey visibility. A concrete fit signal is the emphasis on exception handling, reporting, and lifecycle support in enterprise programs.
A tradeoff appears when the primary goal is quick on-site search enablement without deep system integration or governance needs. This service works best when teams can provide access to product data sources and analytics requirements so Cognizant can configure indexing, monitoring, and operational controls around those inputs.
- +Integration-first delivery for product catalogs and commerce systems
- +Operational controls aligned to governance and exception handling needs
- +Cross-channel analytics alignment for traceable journey reporting
- +B2B integration experience for partner data and legacy modernization
- –Requires strong internal ownership for data access and requirements

How to Choose the Right Ecommerce Site Search
Options differ most in how search results look for real shoppers and how that experience adapts as your catalog changes. Focus on result relevance tuning, especially spelling tolerance, and whether zero results gets a useful path instead of a dead end.
Merchandising and relevance tuning
Why it matters
Merchandising and relevance tuning controls what shows up first when queries are ambiguous. That matters for ecommerce site search because product intent can be unclear.
How to check
On a demo, run 5–10 representative queries (brand, category, short misspellings). Ask how the tool decides ranking, then try a simple rule or boost and re-run the same queries to confirm the change shows up in results.
Spelling tolerance and typo recovery
Why it matters
Spelling tolerance and typo recovery prevents shoppers from abandoning when they mistype product names. Ecommerce search often fails on short, noisy terms.
How to check
Test with common typos for a few products and compare behavior to the correct spelling. Ask whether it handles typos in the same way across query lengths, and whether you can adjust sensitivity.
Zero-result fallback experience
Why it matters
Zero-result fallback experience keeps shoppers moving when nothing matches. In ecommerce site search, a dead end turns into lost conversions quickly.
How to check
Run queries that should have no direct matches (rare SKU fragment, discontinued term, or nonsense string). Check what appears next: suggested categories, popular products, or guided filters; then verify whether shoppers can refine from there.
Faceted navigation for search results
Why it matters
Faceted navigation for search results lets shoppers correct intent without retyping. Ecommerce catalogs are large enough that refinement quality strongly affects outcomes.
How to check
After running a query, open filters and apply 2–3 refinements (price range, brand, attribute). Confirm facets update with the current result set and that common filters are present for your main attributes.
Autocomplete and query suggestions
Why it matters
Autocomplete and query suggestions reduce typing and steer shoppers toward in-stock or correctly named items. This is often the first place shoppers form expectations.
How to check
With a logged-in or demo catalog, type partial queries and watch suggestions change. Click suggestions and confirm they land on results that match the chosen suggestion, not a different intent.
Index freshness and catalog coverage
Why it matters
Index freshness and catalog coverage determine whether new or updated items appear when shoppers search. Ecommerce stores need tight timing with product updates.
How to check
In the demo, provide a way to add or edit a product and then search for it immediately. Verify how quickly it becomes searchable and whether the tool removes out-of-stock or removed items from results.
Red flags
- Zero results show a blank page or only a generic message with no path to browse.
- Typos return unrelated products or behave inconsistently across similar misspellings.
- Updating a product in the catalog doesn’t show up in search within the expected time window.
Fit by situation
- If most shoppers type full product names and expect exact matches, prioritize spelling tolerance and typo recovery.
- If shoppers browse categories after searching, prioritize faceted navigation for search results.
- If you frequently add or retire items, prioritize index freshness and catalog coverage.
