A summary of the changes CodeRabbit can apply:

• Implement a 30-second cooldown cache in src/core/rag/ragEngine.ts by adding two fields (lastIndexUpdateTime and indexUpdateCooldown) and replacing the unconditional call to updateVaultIndex in processQuery with conditional logic that only calls updateVaultIndex if the cooldown has elapsed, preventing redundant re-embedding during rapid @vault searches.

• Add a bugfix doc (docs/BUG_FIX_EMBEDDING_CACHE.md) and modify src/core/rag/ragEngine.ts to introduce caching fields (lastIndexUpdateTime, indexUpdateCooldown) and replace the unconditional await this.updateVaultIndex(...) with a time-based conditional that only calls updateVaultIndex when the cooldown has elapsed.

Thanks for reporting this issue.

There are some known issues in the database/indexing system that can cause unnecessary re-embedding on vault searches. I'll need to take a closer look at this when I have time.

In the meantime, could you let me know if this also happens with other embedding models? This would help determine if the issue is specific to local embedding setups like LM Studio or a more general problem.
