Subject [jira] [Commented] (SOLR-7466) Allow optional leading wildcards in complexphrase
Date Fri, 30 Dec 2016 03:27:58 GMT

    [ https://issues.apache.org/jira/browse/SOLR-7466?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15786764#comment-15786764

Erick Erickson commented on SOLR-7466:
--------------------------------------

Mikhail:

I haven't looked at the code, so take this with a large grain of salt. 

My only concern is if having this on by default would cause a full terms scan. If having this
always on by default means a user can use a leading wildcard without specifying ReverseWildcardFilterFactory
in the analysis chain then it seems trappy.

That said, I'll defer to your familiarity with the, you know, actual code.

> Currently ComplexPhraseQParser (SOLR-1604) allows trailing wildcards on terms in a phrase,
but does not allow leading wildcards.  I would like the option to be able to search for terms
with both trailing and leading wildcards.  
> For example with:
> {!complexphrase allowLeadingWildcard=true} "j* *th"
> would match "John Smith", "Jim Smith", but not "John Schmitt"
