AddSearch is the best choice for teams that need configurable enterprise search with governance and API integration, since its relevance tuning and query assistance live in one admin flow with analytics feedback for continuous iteration, whereas Klevu fits retail teams that want non-engineers to adjust merchandising rules and relevance by query and context.
Editor’s top 3 picks
Three quick recommendations before you dive into the full comparison below — each one leads on a different dimension.
AddSearch
Relevance tuning plus query assistance settings in one admin flow, with search analytics feedback for iteration.
Best for: Fits when teams need configurable enterprise search with API integration and governance controls.
Klevu
Editor pickMerchandising rules combined with relevance iteration lets non-engineers adjust search outcomes by query and product context.
Best for: Fits when retail teams need frequent relevance changes without running their own search infrastructure.
Coveo

Best for: Fits when enterprises need governed relevance tuning across multiple content sources and a custom search UI.
Comparison Table
AddSearch
SMBCloud-hosted site search service with instant indexing and customizable result layouts.
Relevance tuning plus query assistance settings in one admin flow, with search analytics feedback for iteration.
AddSearch targets teams that need managed relevance tuning and predictable indexing pipelines across web and internal document sources. It offers configuration for ingestion, ranking behavior, and query features such as autocomplete and typo tolerance, so search quality can be adjusted without rebuilding an engine. The integration surface includes API access to search and operational endpoints, which helps application teams wire search into product UI and background jobs.
A tradeoff is that teams with highly custom retrieval logic can hit constraints if they need bespoke ranking models or deep engine extensions. AddSearch fits situations where an organization wants fast iteration on query behavior and relevance while keeping the indexing and operational flow under one controlled system.
- +Configurable relevance controls for ranking and query behavior
- +API access for search endpoints and indexing operations
- +Search analytics supports iteration on query outcomes
- +Admin roles limit who can change ingestion and relevance
- –Deep custom ranking models are harder than in full engine builds
- –Complex sources can require careful connector and crawler setup
- –Advanced indexing workflows need operational discipline to stay consistent
- –Cross-source tuning takes time when schemas differ

Best for: Fits when teams need configurable enterprise search with API integration and governance controls.
Klevu
vertical specialistAI-driven e-commerce search and discovery platform with natural-language query understanding.
Merchandising rules combined with relevance iteration lets non-engineers adjust search outcomes by query and product context.
Klevu’s workflow centers on getting catalog content into an indexing pipeline, then iterating relevance using merchandising rules and query terms. The integration surface includes connectors for common eCommerce and content sources, plus APIs for pushing configuration and retrieving search behavior metrics. Search analytics supports decisioning on query performance and result quality, which helps teams keep relevance aligned with catalog changes.
A key tradeoff is that deeper custom retrieval behavior can depend on Klevu configuration options rather than direct Lucene analyzer control. Klevu works well when merchandising and relevance iteration are recurring tasks, such as seasonal catalog refreshes and ongoing synonym and boost management for high-volume search terms.
- +Merchandising controls allow boosting, pinning, and rule-based relevance tuning
- +Search analytics ties query activity to outcome signals for ongoing optimization
- +Connector-first ingestion reduces engineering work for typical catalog sources
- +APIs support configuration automation and programmatic access to search data
- –Analyzer-level control is limited compared with teams running their own search index
- –Advanced ranking customization can require careful configuration rather than code

- +Hybrid retrieval supports lexical matching and vector embedding signals
- +Relevance tuning uses query rules, synonyms, and ranking controls
- +Search analytics provides behavior signals for iterative tuning cycles
- +Connector and ingestion workflows reduce custom ingestion engineering
- –Operational overhead increases with many connectors and content formats

How to Choose the Right Search Software
In search software, the real separators show up in how each option handles query-to-results behavior and keeps search results trustworthy as content changes. We focus on criteria like index freshness, relevance controls, and audit log so you can validate outcomes during a demo.
Index freshness controls
Why it matters
Index freshness controls determine how quickly new or updated content becomes searchable. That timing matters when teams need search to reflect today’s documents, tickets, or knowledge base entries.
How to check
Ask the demo team to ingest or update a small set of documents, then search for a new term and note the time-to-appear. Also ask whether updates can be scheduled or triggered and if the product supports a full reindex versus incremental refresh.
Relevance tuning and boosts
Why it matters
Relevance tuning and boosts let you influence ranking when the default ordering feels off. This is often the difference between “it finds things” and “it finds the right things.”
How to check
Create two nearly identical sample records where one should rank higher by business intent, then try the product’s tuning controls to correct the order. Ask what you can configure at query time versus content time, and whether those changes are explainable.
Filters and facet-like refinement
Why it matters
Filters and facet-like refinement help users narrow results without crafting complex queries. When they work well, search becomes usable for recurring workflows like finding by owner, date, status, or category.
How to check
On a demo dataset, apply at least three refinements (for example date, type, and status) and verify that each one reduces results predictably. Check whether refinements stay accurate after an update by changing one document’s metadata and re-running the same filter.
Query behavior for typos and variants
Why it matters
Query behavior for typos and variants affects whether users get good results when they misspell or use different wording. Teams feel this immediately because real users rarely type perfectly.
How to check
Run a small set of misspelled and variant queries against the same dataset and compare whether results still land in the right area. Ask for an example of how the product handles stop-word removal and term variants, and confirm whether you can adjust it.
RBAC enforcement with audit logs
Why it matters
RBAC enforcement with audit logs protects what users can see and helps admins debug missing results. Without audit trails, troubleshooting access issues becomes guesswork.
How to check
In the demo, use two test user roles with different permissions and confirm that restricted documents never appear in results. Then ask how audit logs record search and access decisions, and whether you can filter logs by user and time range.
API and automation coverage
Why it matters
API and automation coverage determines whether teams can keep search behavior aligned with their operations over time. The depth of automation and configuration reduces manual rework when content and taxonomy change.
How to check
Ask the demo to show at least one workflow using the API: starting an ingestion, updating relevance settings, or running a search with specific parameters. Confirm whether configuration changes support versioning or safe rollback in a repeatable way.
Red flags
- Fresh content takes too long to appear in results after an update
- Ranking changes can’t be explained or reliably reproduced
- Restricted items show up to the wrong roles during demo searches
Fit by situation
- If you update content throughout the day, prioritize index freshness controls to avoid stale results.
- If domain owners disagree on what “best match” means, prioritize relevance tuning and boosts for controllable ranking.
- If users depend on browsing to narrow results, prioritize filters and facet-like refinement for predictable refinements.
