Hi everybody, We recently need to support wildcard search terms "*", "?" together with SpanQuery. It seems that there's no SpanWildcardQuery available. After looking into the lucene source code for a while, I guess we can either:
1. Use SpanRegexQuery, or 2. Write our own SpanWildcardQuery, and implements the rewrite(IndexReader) method to rewrite the query into a SpanOrQuery with some SpanTermQuery. Of the two approaches, Option 1 seems to be easier. But I am rather concerned about the performance of using regular expression. On the other hand, I am not sure if there are any other concerns I am not aware of for option 2 (i.e. is there a reason why there's no SpanWildcardQuery in the first place?) Any advices ?
