Query DSL like queries should only accept % and _ as the wildcards ------------------------------------------------------------------ Key: ISPN-6588 URL: https://issues.jboss.org/browse/ISPN-6588 Project: Infinispan Issue Type: Bug Components: Embedded Querying, Remote Querying Reporter: Adrian Nistor Assignee: Adrian Nistor Fix For: 9.0.0.Alpha2, 9.0.0.Final The official wildcards are % and _. But users can mistakenly use * and ? and those will usually work too. This works because the * and ? are valid wildcards in the underlying Lucene query language. But this breaks if the query is supposed to be run un-indexed for whatever reason. To fix this we need to escape * and ? from user's input so they are no longer internally handled by Lucene as wildcards. These chars should cause an exact match instead. The actual recognized wildcards should be only % and _.
