[jira] [Commented] (LUCENE-5378) Enable using extended field types with prefix queries for non-default encoded strings

["Yonik Seeley (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LUCENE-5378?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13857132#comment-13857132 ] 

Yonik Seeley commented on LUCENE-5378:
--------------------------------------

readableToIndexed may not work well with some types... perhaps we should have a
FieldType.getPrefixQuery(SchemaField sfield, String prefix, QParser qparser)

> Enable users to be able to use prefix query with custom field types with non-default encoding/decoding for queries more easily. e.g. having a custom field work with base64 encoded query strings.
> Currently, the workaround for it is to have the override at getRewriteMethod level. Perhaps having the prefixQuery also use the calling FieldType's readableToIndexed method would work better.
