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.
