- Check restrictions/limitations in question above.
- If you are migrating a database, (a) make sure there are no invalid objects in the source database before making the export.
- Take a full norows export to recreate objects that won't be transported with TTS.
- Keep the source database viable until you have determined all objects are in the target database and there are no issues (i.e. the target database has been thoroughly checked out and exercised).
- Do a dry run to work out any unexpected issues and determine timings.
We'll explore scenarios involving nested queries, aggregations, custom scoring, and hybrid queries that combine multiple search criteria. 1. Nested Queries ElasticSearch Example: ElasticSearch supports nested documents, which allows for querying on nested fields with complex conditions. Query: Find products where the product has a review with a rating of 5 and the review text contains "excellent". { "query": { "nested": { "path": "reviews", "query": { "bool": { "must": [ { "match": { "reviews.rating": 5 } }, { "match": { "reviews.text": "excellent" } } ] } } } } } Redis Limitation: Redis does not support nested documents natively. While you can store nested structures in JSON documents using the RedisJSON module, querying these nested structures with complex condi...
