Analyze_wildcard performance impact


(chimingc) #1

The query_string parameter analyze_wildcard is off by default.
We are considering to turn it on for better search results, but are concerned about the performance impact.
Anyone have experience on this? Recommendation?

Thanks

It just means that the wildcard text will be analyzed, the performance
impact will come from the fact that you use wildcards (regardless of the
analysis or not), as they are very heavy, and usually solved better by
using custom analysis like ngram or stemming.
