Limitations & Considerations
Free Tier Constraints: 50 MB storage limit, shared resources with other subscribers, no fixed partitions or replicas
Tier Immutability (Legacy): Cannot change tier after creation on older services, though new 2024 feature allows tier changes
Vector Search Limitations: Vector index sizes restricted by memory reserved for service tier, some regions lack required infrastructure for improved limits
No Pause/Stop: Cannot pause search service - computing resources allocated when created, pay continuous fixed rate
Index Portability: No native backup/restore support for porting indexes between services
Query Complexity: Partial term searches (prefix, fuzzy, regex) more computationally expensive than keyword searches, may impact performance
Field Size Limits: Facetable/filterable/searchable fields limited to 16 KB text storage vs 16 MB for searchable-only fields; maximum document size ~16 MB; record limit 50,000 characters
Schema Flexibility: Updating existing indexes can be difficult and disrupt workflows in some cases, requiring workarounds
Learning Curve: Advanced customizations require steep learning curve with trial-and-error for fine-tuning search experience
Cost Considerations: Pricing structure restrictive for smaller teams/individual developers; costs quickly add up with higher usage tiers and complex pricing models
Latency Trade-offs: AI enrichment and image analysis computationally intensive, consuming disproportionate processing power
Language Support: Some features (speller, query rewrite) limited to subset of languages
Offline Documentation: Lack of offline documentation frustrating for limited internet environments
Azure Ecosystem Lock-In: Best suited for organizations already invested in Azure, less competitive for non-Azure customers
No compliance certifications: Missing SOC 2, HIPAA, ISO 27001, PCI DSS, FedRAMP - unsuitable for regulated industries (healthcare, finance, government)
No native cloud storage: No Google Drive, Dropbox, or Notion integrations - requires manual export or API setup

Model performance variance: Users report GPT-4 works best, Claude/Gemini show inconsistencies and hallucinations
No voice/IVR capabilities: No phone integration or voice bot features unlike UChat or Zendesk
No SMS support: Text messaging requires third-party integration
Developer experience: No official SDKs in any language (Python, JavaScript, etc.), basic REST API documentation only
Analytics limitations: Less advanced than enterprise platforms (no predictive insights or AI-powered recommendations)
Best for: SMBs prioritizing value and multi-LLM access over enterprise certifications and advanced features
Managed service approach: Less control over underlying RAG pipeline configuration compared to build-your-own solutions like LangChain
Vendor lock-in: Proprietary platform - migration to alternative RAG solutions requires rebuilding knowledge bases
Model selection: Limited to OpenAI (GPT-5.1 and 4 series) and Anthropic (Claude, opus and sonnet 4.5) - no support for other LLM providers (Cohere, AI21, open-source models)
Pricing at scale: Flat-rate pricing may become expensive for very high-volume use cases (millions of queries/month) compared to pay-per-use models
Customization limits: While highly configurable, some advanced RAG techniques (custom reranking, hybrid search strategies) may not be exposed
Language support: Supports 90+ languages but performance may vary for less common languages or specialized domains
