Possible disadvantages of Apache Solr

• Complexity
  The initial setup and configuration of Apache Solr can be complex, particularly for those not already familiar with search engines and indexing concepts. Managing a distributed Solr installation also requires considerable expertise.
• Resource Intensive
  Running Solr, especially for large datasets, can be resource-intensive in terms of both memory and CPU. It requires careful tuning and adequate hardware to maintain performance.
• Learning Curve
  The learning curve for Apache Solr can be steep due to its extensive feature set and the complexity of its configuration options. New users may find it challenging to get up to speed quickly.
• Consistency Issues
  In distributed setups, ensuring data consistency can be challenging, particularly for users unfamiliar with managing clustered environments. There may be delays or issues with synchronizing indexes across multiple nodes.
• Maintenance
  Ongoing maintenance of a Solr instance, including monitoring, tuning, and scaling, can be labor-intensive. This requires dedicated effort to keep the system running efficiently over time.
• Limited Real-time Capabilities
  Although Solr provides near real-time indexing, it may not be as effective as some specialized real-time search engines. For applications requiring truly real-time capabilities, additional solutions might be necessary.

  Relying on Google Custom Search means relying on Google’s ecosystem, which could be a risk if there are future policy changes or if the service is discontinued.
• Data Privacy Concerns
  Some organizations might have concerns about data privacy and control, as the search data is processed and stored by Google.
• Keyword Restrictions
  Certain keywords and search terms might be restricted or censored, limiting the scope of searchable content based on Google's policies.
• Cost for Advanced Features
  Access to advanced features and higher query limits requires a paid subscription, which could be a significant expense for large-scale or heavily trafficked websites.
