Common questions
Frequently Asked Questions
How do I convert CQL to Elasticsearch?
Paste your CQL code into the input box, confirm the languages are set to CQL and Elasticsearch, and click Convert. CodeConvert AI analyzes your CQL code and generates equivalent Elasticsearch code in seconds, preserving the original logic and structure.
What are the main differences between CQL and Elasticsearch?
CQL and Elasticsearch differ in syntax, type system, standard libraries, and common idioms, so copying code line for line usually will not compile. The converter maps each CQL construct to its closest Elasticsearch equivalent. See the comparison table below for the key differences between CQL and Elasticsearch.
Is the converted Elasticsearch code accurate?
The AI produces high-quality Elasticsearch code that preserves the behavior of your original CQL code and follows Elasticsearch conventions. It handles common patterns, data structures, and idioms for both CQL and Elasticsearch. For large or performance-critical code, review and test the Elasticsearch output before using it in production.
Can I convert an entire CQL project to Elasticsearch?
You can convert CQL files one at a time by pasting each file's code. For a full migration, convert each file and then review how classes, dependencies, and project structure map from CQL to Elasticsearch. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.
Can I convert Elasticsearch back to CQL?
Yes. CodeConvert AI converts in both directions, so you can convert Elasticsearch to CQL just as easily using our Elasticsearch to CQL converter. Try the Elasticsearch to CQL Converter
Is the CQL to Elasticsearch converter free, and do I need to install anything?
Yes, it is free and runs in your browser with nothing to install and no IDE extension required. You can convert CQL to Elasticsearch without an account for up to 2 conversions per day. Sign in for free for higher limits.
