We need to make sure that the completion suggester is able to handle our search traffic.
If performance is an issue with the current configuration we will be able to tune it with :
- Increase the number of shards (4 shards today vs 7 for prefix search)
- optimize, the index is read only, optimizing the index to one segment will help
- tune various suggestion parameter (prefix len, fuzzyness ...)
- Remove the 2nd pass query
