I ask the question in http://lucene.472066.n3.nabble.com/A-little-onfusion-with-maxPosAsterisk-tt3889226.html However, when I do some implementation, I get a further questions. 1. Suppose I don't use ReversedWildcardFilterFactory in the index time, it seems that Solr doesn't allow the leading wildcard search, it will return the error: org.apache.lucene.queryParser.ParseException: Cannot parse 'sequence:*AAAAA*': '*' or '?' not allowed as first character in WildcardQuery But when I use the ReversedWildcardFilterFactory, I can use the *AAAAA* in the query. But as I know, the ReversedWildcardFilterFactory should work in the index part, should not affect the query behavior. If it is true, how does this happen? 2.Based on the question above suppose I have those tokens in index. 1.AB/MNO/UUFI 2.BC/MNO/IUYT 3.D/MNO/QEWA 4./MNO/KGJGLI 5.QOEOEF/MNO/ suppose I use the lucene, I can set the QueryParser with AllowLeadingWildcard(true), to search *MNO* it should return the tokens above(1-5) But in solr, when I conduct the *MNO* with the ReversedWildcardFilterFactory in the index, but use the StandardAnalyzer in the query, I don't know what happens here. The leading *MNO should be fast to match the 5 with ReversedWildcardFilterFactory The tailer MNO* should be fast to match 4 But What about *MNO* ? Thanks!
